About This Class

This course is an excellent sequel to the Designing For 3D Printing with Fusion 360 course by Vladimir Mariano.  We learn how to tackle a multi-part design by taking advantage of using components and other powerful design tools in Fusion 360.  We will design an LED tea light that functions as a mechanical switch and can be used to light up our other 3d prints.  It's an excellent example of using 3d printing for practical and functional designs.

At the end of this course you will have gained the design skills and confidence to take a multi-part design from concept to 3d printed prototype. 

We will cover many sketching and modeling concepts and also go through some best practices when designing for 3d printing such tolerances needed for a snug fit when assembling two or more parts.

I will guide you through easy to follow step by step instructions as we create a rewarding model.

1. 01 Itroduction: hi and welcome to Fusion 3 60 for three D printing design and led T light. If you've taken my previous class, then you know that I like to design things that are very practical and functional, and this is no exception. This design came about because I wanted a simple way to light up some of my three D prints . For example, this lamp, a giant crystal pumpkin, never TD or even some kryptonite. This design looks simple on the outside, but there's quite a bit going on on the inside. We will use the powerful design tools infusion 3 62 essentially model and led tea light that also functions as a working mechanical switch. The model will also allow me to teach how to tackle multi part designs by taking advantage of using components Infusion 3 60 At the end of the course, you will have designed and led tea light that switches on and off by simply using an led a coin cell battery and your three D printed parts. You can then take the skills learned in this course to modify the design to fit your own specific application. This course is designed for those that already have a basic working knowledge of using fusion. 3 60 if you're a complete beginner, and then check out mine designing for three D printing with fusion 3 60 course if you're just getting into three D printing, and then this is the perfect course to improve your design skills and build your confidence in being able to take a design from concept to working prototype. Plus, you'll end up with a working led lamp that you made on your own. My name is Vladimir Mariano, and I teach designing for three D printing at various local schools. I look forward to having you join my course. 2. 02 Parts Needed: let's quickly go over the parts that will be using. And besides our three D printed parts, this simply includes are led and our battery for the led. I'm simply using a standard five millimeter led that you can pick up in numerous places. For example, if you have a radio shack still open, you can just pop in and grab a few of these. Otherwise, Amazon is a great source. Just a quick search of five millimeter led. We'll bring up a bunch of different variety packs that you can just grab for a few bucks. I also found eight of fruit to be a great source, and they're a great source in general, just for electronic components. But you can buy these 25 packs of LTD's for just four bucks, and you can choose whatever color you want. They've got a good stock of these. As far as the RGB led is, I was able to find those in our on eBay. Um, in these are great because they were just like the regular led is. They only have. The two leaves were usually RGB led is tend to have four leads, Um, but these only have two. And so you can wire him the same way, and they just cycle through the colors. Um, so there the slow color, changing led ease. And they really work great in a bunch of different applications where you just wanna have it sort of cycle through a bunch of colors without worrying about any programming. So those are a I was able to find on eBay, and I'll leave the link below, um, where you can get these Aziz. Well, as all the other parts, Um, so let's move on to the battery. Now for the battery, I'm using this c R 2032 coins, cell battery and these air three volt batteries. And again, Ah, Amazon was just a good spot just to grab a bunch of these for just a few bucks so you can check out the different prices there. I was able to get lucky and that I just walked into our local dollar store and I found that they have these where they sold them in packs of five for a dollar 99. So that's a great place. Just stop at your local dollar store and see if you can get thes pretty cheaply. Otherwise, I found that, you know, the pharmacies tend to sell these. Um, you know, they tend to be pretty expensive. So I would first try a dollar store or tried Amazon. Um, and that's basically all the parts that will need. 3. 03 How it Works: Let's not talk about the mechanics of how this actually works and we'll start with the battery so a battery will have a positive side. And if we flip it, we have the negative side. But an important thing to note also is that the site of the battery is also positive. So we have positive on top in other side and negative on the bottom. Now, the led also has a positive in the negative side. So we have a long leg in a short leg, shortly being the negative side and long leg being the positive side. Now, if we line up the battery and the led and we match up the corresponding size so that we have negative and positive lining up, our led will turn on notice. If I flip it the other way, nothing happens. So the idea here is to wire are led so that we have negative going through the bottom and positive connecting on the side. And when we put in our battery, if I put in a negative side up, so our sides correspond, nothing happens. If the led his own led is only connected with negative side notice, how if you can see this side here is not touching. But if I move the battery over so that I complete that circus for that I'm now touching both the negative in positive side our lady will turn on so I can simply turn on and off the already simply by moving that battery back and forth. So that's where this design comes in. So if you look here, you notice that we have this channel that comes in through Dan's higher part and that whole channel is uninterrupted. Besides, this part over here that has a little flip it a little bump. How right here might be hard to see in this image, but you'll clearly see it in the model, and we're gonna go ahead and model that it. And the reason for that bump out is that when we bring this part into play, this part also has these little bump outs here. And also notice the bump out here corresponding to our little arrow in this top piece right here. So what's going to happen is when we insert this part and to hear once this bump are corresponds with this bump out here, what it's what it's going to do is push that battery. This battery will be unlike this. It's gonna force that battery over to this side and force it to connect. Sure. Get the view here. Makes it'll connect this positive side. It'll make sure to connect it with the battery in order to close that circuit. And then the opposite of that will be that this part will turn in this bump out here. Well, then line up with that, um, positive side of the led, then closing that circuit. So basically, we're just gonna be turning this peace to either black that connection or force it to make that connection. Um, and that will become a little more clear as we get into modeling the actual part. 4. 04 Designing with Components: before we begin, I'll just quickly go over all the parts that we will be making. So as you can see here in the left side of my browser, I started with a battery which will go ahead and make that we were not gonna print it. But it's just nice reference to have Ah, you know, Then we have our bottom part, which are about batteries. Gonna sit on. We have what I call the top portion, which is gonna hold the led, and then we also have a cover. Now, as you can see, everything here is organized into components, which makes it very easy when we have to come back and tweak something. So, for example, right now I have the whole top part of my drowsy here activated. So, Aziz, you can see it. My entire timeline is shown below. So if I wanted to go ahead and say, Let's for example, show the battery here and I realized Oh, you know what? This is 10 millimeter radius. I actually wanted, uh, let's say a 24 millimeter radius. Well, if I try to go back and change that, that's gonna be a pain, because it's gonna be if I haven't used components. This is what I would see and trying to figure out which of these sketches controlled that the mention would be a nightmare. But the fact that I have this into components, I could just go ahead and activate that component. And now that shows me the to outline features that I have for that battery. So now I'll have to do is just go into that sketch and say, OK, so that's my diameter. I can go ahead and make this 24 and then just stop sketch and there we go. You know, that radius is now 12. So very easy to fix here because in that battery component there were only two features. It was just simply a sketch. And then extrude, um, so shows you the power of organizing your models and two components. Whenever you're doing more than one part, I've gotten myself into situations where I've just been lazy, starting a drawing or just not thinking ahead with my model and, you know, have ended up in cases where, um, I have multiple parts. And then I'm looking at that time line and, you know, just regretting that separating into components. So I'm gonna go ahead and undo that last change because I want that battery to be 20 millimeters Stop sketch. And so let's go ahead and activate everything again, as you can see here, all my parts on and I gave him each just a different color, just to be able to distinguish it a little better. But we'll go ahead now and jump right in, and we'll start with the battery and model each part. 5. 05 Configure Z up: Let's go ahead and create a new design by clicking on file in new design and go ahead and turn on the origin lightbulb here. Now, as you can see, Fusion three sixties default is to have. Why are the y axis as facing up now, in all of the three D printing applications I've seen, Z is always up. So the problem is, if you design something with, ah this orientation of white up, then you export into a three D printing application a slicer, for example. You're always gonna have to rotate it. So in order just to avoid that, let's go ahead and change the setting so that Z is going to be up. In order to do that, we're just going to click on our name here on the upper right hand side and go down to preferences. Now, under general, you'll see where it says default modeling orientation. Go ahead and change that from why Up to z up, click, apply and then click. OK, now if we click on the home will notice that it still hasn't updated in order to get it to update will have to close on this file and then opened up a new one again. So file in the design. Now when we click on the origin will see that RZ is up. 6. 06 Sketch Constraint Status: Let's now go ahead and modify our preferences so that when we have a sketch fully constrained, it's going to let us know by changing colors and I'll show you exactly what I mean. So if I create a sketch here, I'll just go ahead and places sketch on the X Y plane, and I'm just gonna go ahead and draw a circle. Now the circle is blue, as you can see, and I haven't set any constraints to it, right so I could move it up or down, Left or right. Aiken, grab on the perimeter here and change the circumference given in a bigger or smaller diameter. Um, so there's no constraints, so it's really able to move, and then I can start adding some constraints to it, right? I can give it a diameter here by say, I'll enter 30 millimeters, and I can also give it a distance from this origin. Let's go ahead and make this say 50 millimeters, and so we start adding some constraints. So right now I can see that I can I can't change the diameter anymore by moving it, Um, by grabbing the perimeter, moving it, um and I can't push it left or right because it's set to be 50 millimeters from this origin . But I can still move it up or down, right? So it's not yet fully constrained, so I can go ahead and add one more constraint to this. And let's say I grab the, um, grab this horizontal slash vertical constraint. And so let's I wanted on the origin here or on that the axe access here. So I'll go ahead and constrain this how? Grab the center of that circle and click on my origin. And that's going to go ahead and make it horizontal to this lie so you can see that it changed from being blue to being black. That lets us know that Mrs now fully constrained. I can't do anything to this anymore. Cankers of diameter. I can't move it left or right, and I can't move it up or down. So to have that effect, where it changes colors that doesn't come the fault. You have to actually enable that. So to do that, we're gonna click on the upper right hand side where our name is, click on the arrow and then go down to preferences and under preferences. We're gonna go down to preview and you're gonna want to make sure that this button is checked right here, where it's a sketch color sketch geometry based on constraints status. So go ahead and check that click. Apply, then click OK, and that will go ahead and enabled that feature for you. 7. 07 Designing the Battery Component: Let's go ahead and save our design. So we'll click on safe and gonna call this led T light and go ahead and choose your location. You can either create a new project folder or saving in an existing one. I'm just gonna choose one of my existing folders and click safe. Okay, Now we're ready to create our first component. So to do that will right click on the top of our browser, which has the name of our model, and go to new component. Now you'll see under here, you'll get this new box that pops up, which says, Just component. And it's got a box, which is the icon for component. Let's go ahead and double click on that. And we're gonna name this battery. Go ahead and hit. Enter. Um, I noticed. Well, sometimes when you double click, you cap to do a little bit slow. If you double click really fast, sometimes it doesn't light up. So what I do is click ones and then wait a second, then click again. I don't know. That's just a little tip that I found out what happens. Um, so you're having trouble choosing that name? Just click double quick, but DoubleClick slow. Okay, so now we're ready to start our first sketch here. So we see that we have our battery component and we have this radio button. It should automatically be activated. If not, just click on that button. And now we can go to sketch, create sketch, and we'll start this catch on the X Y plane here, so we'll click there to start drawing. Um, just gonna go ahead and start with a circle so we'll do a sense her diameter circle, and we're gonna give this a diameter of 20 millimeters and that's it. We can click, stop, sketch, and then I'm gonna hit he for extrude. Go ahead and click on my profile. Go up. We're gonna make this just the three millimeters and hit Enter, and that's it for our first component. So next we'll go ahead and model our second part 8. 08 Sketch and Revolve: our next part is going to be that top portion of our assembly where are led is going to be sitting. So let's take a look at it before we start modeling. So I'll switch over to my other design here, the completed one. And here it is. So you can see we have the cylindrical shape. Ah, which we're gonna obtain this shape by first just creating a sketch in revolving. It noticed these, um, trenches in the middle here where are led. The legs of the led will, uh, will be inset into and in plus within the middle, you'll see that there's another sort of trench under inside here. Plus our holes that are led legs will go through. So I just wanted to give you a quick overview of what that's going to look like. I know. Let's go ahead and make it so we'll switch to our current design and we'll start off by creating a component again. So we're going to right click and choose new components again. We're gonna rename this, so we're gonna call it. We'll just keep it simple and call it top, and we're ready to create a sketch. So we'll go to sketch creates catch. And as far as our plane will go ahead and choose this blue red plane or rz explain and you can see the outline of our battery there. That's because we have that light bulb toggled on. Um, in this case, it's nice to have it. You can see it's transparent so it doesn't get in a way, plus allows us to reference it and our next drawing. So if you do want to get rid of that, you just title it off. So we'll start with just this basic line sketch. So I'm gonna hit l for a line, and you do want to keep in mind It just makes this go a lot smoother. If you are aware of sort of the dimensions you're gonna be working with now, I know I wanna make this 13 wide bites wealth 12 deep, and I don't have to get it exactly for not. But I want to be within, you know, within that range. So I'm just gonna go ahead and start somewhere here, go up, you know, So you know, close to 13 or so and then I'm gonna go down close to 12. And you know, I know that I want this to be about two miller to millimeters. So I was gonna get close to those dimensions but not worry about getting them exact. And I'm referencing the top part here so I can get that straight line and close this off. Now I have my shaded in profile. Um, Now I'm gonna go ahead and answer my dimension. So to do that, I'll just hit D for dimensions and go ahead and make this 12. I'm gonna make this 13. Actually, I got that backwards. So we're just gonna double click here. I want this to be 13. And let's move this out and I'm gonna click that and make that 12. Let's make this bottom too. I also make this to here and all right, so that's the basic shape that I want. Now I'm gonna go ahead and hit l for a line and make a vertical line from my origin. Click the check mark, and I'm gonna make that into a construction life. Now, I'm gonna enter some constraints here, so I want this line to actually be vertical with this line or be Colin year with that. So I'm gonna grab the coleene, your constraint, grab this line and click on the construction line I just made. And now that's Colin year. Um, I also know that I want the top portion here. Ah, specifically this line here to be, ah, half a millimeter from the top of my battery, because when the led legs go in, they're gonna basically, um, occupy the space between that and I measured them. And I know that their 0.5 millimeters So I'm gonna hit D for Dimension and go ahead and dimension of the the origin here from the top or from the this line here and bring that out . I know that, my lady or my battery is three millimeters, So I'm gonna make this 3.5 millimeters, and that brings that right into place. So as you can see, this whole thing turned black. So it went from blue to black, so it's fully constrained, meaning I can't move it in any way now. So next What we're going to do is create the feature here that's gonna allow us to extrude this channel and the inside. And to do that, we're just gonna create a circle. You just draw a circle on this line and I'm gonna make that circle 2.5 millimeters. And I'm gonna dimension that circle from the bottom edge to be 3.5 millimeters. So that's basically all I need now and so I can go ahead and click stops catch and I'm gonna go to create Revolve, choose that profile and a SMI accidents. I'm going to click on it and I'm gonna choose, You know, I convert and choose the blue accidents here either The blue accent sort of construction nine I made and that will go ahead and revolving. I'm gonna keep it at 6 360 degrees nobody and click. OK, and you can see that we have that shape in there with that channel in the middle. Um, our battery is still there. We can see it weaken. Title that off can also Tyrell off our origin, so you should have a shape that resembles this and next will go ahead and move on to our next step 9. 09 Sketch on Top Surface: we're now ready to go ahead and create these holes and these channels on the top and side of our model. So we'll go go to our current design and make sure we're still active on this component. So make sure top is activated and we're gonna go ahead and click on sketch creates sketch, and we'll choose the top of our model, and we'll start by first just creating some circles. So I'm gonna hit, see for a circle and draw a circle close to this horizontal line here. And I'm going to give this a diameter of 1.5 millimeters and we'll go ahead now and set a horizontal slash vertical constraint between our circle and the origin. Now, the way that horizontal slash vertical constraint works is that it will constrain it to whichever is closer either vertical or horizontal. So if he would have drawn this circle over here and then clicked on the origin, it would have made it vertical instead of horizontal. So next we'll go ahead and create a second circle. Now, we can do this different ways, but I'm actually gonna go ahead and choose my circle Hit control. Uh, see, to copy a commander for an iMac and control V to paste and gonna go ahead and just move that over. And now that gave me my second circle. So we'll now go ahead and ah, constrained that 2nd 1 as well to be ah, horizontal. So grab that constraint, click on the mid point and click on the center. And there's our constraint so we can see we can move this left to right. We can't move it up or down. So to go ahead and constrain it further, we're gonna answer some dimension. So I had different dimension. The mention it between the center, so center and the center of the circle or origin and center of the circle. And we'll set that first to mention to be 1.5 millimeters. And I'm gonna hit Deford to mention again. And I know I want this second circle to be six millimeters from that first circle. All right, so next I'm gonna draw a couple of lines. Something had l four line, and I'm gonna draw one life from this circle to the edge of my perimeter there, and we'll go ahead and also constrain that line. Give it a horizontal constraint. And we'll draw second line from this circle out and will make that four millimeters. So I'm gonna go ahead and hit the for dimension and make this four millimeters. Okay, so that looks pretty good. Everything is all back black. So it's fully constraint. So I'm gonna go ahead and click on stop sketch and will now continue to make our other sketch on the side. 10. 10 Sketch on Side & Pipe Command: Let's not go ahead and create these holes and these channels on the side of the cylinder. So to do that, I'm gonna go back to my current model, and we're gonna create eight an offset plane so we'll go to construct offset plane. And I'm gonna go ahead and toggle on orange in here, and I'm going to select this blue. Why? Um, plane. So that's our Z. Why? And there's a few ways I can select that I can, actually, you know, if I highlight over here, I could grab the top. You have to be careful, because if you hover over the top here, it may think you're trans like the top plane of the cylinder. Um, otherwise, you know, you can try their, you know, grab it here. What? You can also left, click and hold. And if you do that, you'll see you'll get that to pop up on the menu here. You also have the option of just turning off that body and the what I wait. Everything kind of gets out of the way. Um, and turning off that sketch in another way you can actually select is just if you expand origin here. You'll see you'll have access to all your planes so we can choose that Y Z plane right here and next. We'll go ahead and take this arrow and move it out. You can see if I go left. It goes negative. If I go right, the value goes positive. I know that my radius here is 13 millimeters. So I want this to be right on this edge. So I'm gonna go ahead and ends her negative 13 right on the dialog box. Now I have a plane right there. That's tangent to that side that I can create a sketch so we'll go to sketch creates catch . I'll choose that plane, and I'll start the same way by creating our circles. So I'm gonna create my first circle, give it a diameter of 1.5 millimeter. Gonna grab my constraints. My horizontal slash vertical constraint constrained that circle, um, vertical with this origin. And I'm gonna dimension that to be three millimeters from the top. I'm gonna create a second circle, so I'll go ahead and do it the same way. Minute hit Control C for copy and control V for paste. I have to make sure actually select my circle first. So let's try that again. Control C and in control V. Uh, okay, here's another tip. Make sure you escape out of whatever selection you have. So if I had D for Dimension that the mentions days there waiting for me to select my next dimension the same thing with constraints if you select the constraint, um, you'll be you'll have that constraint active until you had escaped. So let's try this one more time. I'm gonna hit escape, and then I'm going to select my circle hit Control C and in control of E. And then now I can actually move a copy of that circle down. I'm gonna dimension this circle to be three millimeters from my first circle, so many three and enter and we can see it's still blue, so it's not fully constrained. Turns black once it's fully constrained, so it looks like we could move it left to right. You know, we can't move it up and down. So let's grab a vertical constraint here and grab the circle, and we'll go ahead and constrain it to this origin and their regards. And now it's fully constrained and we'll go ahead and now draw some lines. So I help for line, and I'm gonna choose the top point here and come down to the center of that circle, and then I'm gonna grab a second line. Um, And if this is annoying to you, that this keeps highlighting on and off and just toggle this body off. And so our second line is gonna be from this, um, circle here that's gonna go out. So I'm gonna hit l for line, and I'm gonna draw this out, but I can see that this line here is gonna get in the way. So you know, you can always move these dimensions. Thieves were work a lot better on this side, so I was traded again. L four line. Start with that centre diameter, Come out. And I'm gonna make this like a check mark on D for Dimension. And I'll make this four millimeters and had answer eso I'm all set. So many click stop sketch will toggle our body back on. And now we're all set to go ahead and extrude these circles and also our channels here. So let's go ahead and do that. I'm gonna untangle origin here. And as far as our circles, I'm just made he for extrude will start with the top ones. I'll select this one and this one and go ahead and grab the arrow. Bring it down. We could see that it goes all the way through the bottom. But instead of giving it a distance, I'm just gonna choose for extents. I'm gonna choose all click, OK? And we can see that tackles all the way through Now we'll do the same thing for these side ones, so I'm gonna e for extrude select both circles. Gowin, um, checking the bottom to see that they're going through now if I hit, uh, if I change distance to all for this one, it's actually gonna go all the way through, so I don't want to do that. So, for this case, I'm just gonna drag it back and just confirmed that it goes all the way through that curve there and then click. Ok, All right, so now let's create those channels. My sketch has disappeared, so I'm just gonna left are click on the left side here, that arrow and go ahead and turn on. That's my sketch number three and also turnouts. Catch number two. So to create these channels, I'm gonna use the pipe command. So I'm gonna go to create and go down to pipe, gonna choose this one, and I'm going to give it a diameter of 1.5 millimeters. And go ahead and make sure it says cut and I'm gonna click. OK, I'm going to repeat that. Commanders by right clicking and shoes. Repeat pipe. Choose this one as well. Give that the same diameter. So we're choosing 1.5 and I'm going to repeat it a third time. Choose this one again. 1.5 and final time. Repeat pipe and shoes that and make it 1.5. So I'm gonna get rid of sketch now. And we should have, uh, this model with our holes and our channels carved in 11. 11 Side Opening: next, we'll create this opening right here. So we'll go ahead and do that by creating a sketch right on the bottom side of our cylinder and will create that opening on the bottom part here. So to do that, we'll go ahead and create a few lines. First, we'll start with a line for Amar Centre Street down. Make sure you get that vertical constraint. We're gonna click our line and had acts to make it a construction life. Next, we'll go ahead and create another line. This time we're gonna go from the origin out to the perimeter here, and we're gonna Deford dimension, and we'll dimension this to be 40 degrees. Now I can create another line on this site, but on still, go ahead and mirror that light. So I didn't choose mirror, choose the line, select Merah line on the dialogue box and choose that construction line we made and then click OK, and there is our married life. So I want to extrude this, um, this section right here so I can get you for extrude. Actually, once I did that, I lost my sketch. Sometimes it entitles this catch, so title that back high. I'm select that profile again and drag this up. Now, I want to go from the bottom here to the top of that, um, on the top of this channel here. And I can't remember what that WAAS So I'm gonna go ahead and click on cancel here, and I'm gonna go ahead and toggle or double click on that first sketch. First, I'm gonna need to stop this sketch, click on stop sketch, and then go back to my timeline and double quick on that first sketch I made. And so what I want is to know that them the mentioned between the bottom here and the top of that channel which was created by this circle so d for dimension Choose the bottom portion here, and I'm gonna choose. Uh, it won't let me grab the top of that circle. So let me go ahead and put in a point. So I'm gonna go to sketch. I'm gonna go to a point and I'm gonna stick a point right there. Now I can go ahead and choose D for dimension measure between that point and the top or the bottom in the top of that point and click. OK, it's gonna tell me. Oh, you're gonna make this, um, you know, you're over constraining this basically. So I'm gonna find with that look like okay, because all I really want is to know that number. And I could have added this, but I wanted to show you how you can actually just go ahead and get that. So I know that that's 4.75 from the bottom top, that channel. So now I can click on Stop sketch and try that again. I'm going to bring back my sketch. Haiti for extrude grabbed that bottom profile. Bring it up and I'm gonna enter negative 4.75 And that will take me right to the top of that channel. I'm gonna head answer. 12. 12 Bumpout: next. We're gonna go ahead in create this part here, this sort of bump out that we see from within that channel. And that's the part that's gonna be critical for when we turn that bottom portion of our design here. Basically, what's gonna happen is that's what's gonna push the battery to be to make that connection with this side and get that electrical connection happening to turn on our led. So it's a very important part of the design. Let's go ahead and make it so back to our current design. We're gonna start again with a sketch on this surface here. So we're gonna go to sketch, create sketch and choose that surface now, We wanted to be on this side. Um, actually, we wanted to be on this side because that's where our led is gonna threat through the leg of the led. So we'll go ahead and start drawing here. Um, go ahead and expands catches, and I'm gonna untangle all the previous caches besides the current one I'm working with. So I'm gonna go ahead and create eight and arc, so I'm gonna choose are three point arc, and I'm going to start this arc. Be careful not to select in the mid point, cause I don't want that constraint so anywhere. That's not the midpoint. It's fine. And I'm gonna select the middle here and this red access like, and then I'm gonna go ahead and set the bulge. And in this case, I'm just gonna come out. Oh, ah, Over here is where it's snapping. I'm just gonna come in a little bit until it snaps again. So we have it snaps ones, and I'm gonna come back just to give it around. You know, this type this curvature here. If you if yours resembles something like this, you should be good. Uh, next I'm gonna have deferred to mention I'm just gonna dimension this end from here, and I'm gonna enter 0.8 millimeters. So we have that. And next, I'm going to go ahead and draw a line from the center out to make this a construction line , and I'm gonna go ahead and mirror this arc that I just made. So I'm gonna choose catch mirror, choose my art, But I also want this line here, so I'm gonna choose that as well. And I'm gonna ask for my mirror alignment. Choose that construction lines and then click. OK, and I'm going to click on Stop sketch. Now, I'm going to go ahead and choose that profile. Yay for extrude! And I'm gonna go ahead and extrude that down. And instead of cut, I'm a choose join, And I'm just gonna make sure I go all the way through in this case. Click okay? And then I'm gonna hit f for fill it and just fill it this edge. And, um, you just go ahead and go win until it's gonna be pretty large for that, you're gonna get to some point where nothing is gonna happen. So, um you see, that's just fill out of 100 and just to give it and sort of, ah, transition from where it goes up and then back down again. Okay, so once we do that, we're all satin week and, uh, zoom out, in its view, are our model here? That's pretty much everything. So that concludes our second component. So make sure to go ahead and click Save 13. 13 Sketch and Revolve: we're now ready to model the bottom part of our assembly. This is the part where the battery is going to sit, and the part that we're gonna be twisting left or right to go ahead and turn on or off our led. So just a quick overview of what it looks like, and we'll go ahead and jump right in. So I switched to my current model of here by just clicking on this tab, and that will begin by creating a new component. So I'm going to right click on the top of our browser here, choosing the components, and we'll go ahead and name this one bottom, and I don't need to see the top part or the top components. So I'm gonna just go ahead and unclipped that light bulb and I'll show our battery because our battery is going to be sitting right on top of this part. So it'll be nice to have that reference. Um, next, I'll go ahead and create a sketch so I'll just go to sketch, create sketch, and I'm going to choose this blue red or dizzy. Explain. So click on that and I'll just start. Ah, you know what? The same approach that we did our top components. So I'm gonna hit the l key for line, and I'm just gonna draw the basic shape. Then we'll come out, come back and put the dimensions. So what started the origin? I know that I want this to be roughly 10 millimeters out, so I'll go to about that extent, um, come down, you know, roughly eight or so, and then go ahead and start just getting my basic shape that I'm gonna reference that origin and click there. So that that gives me that straight line. Um, you can see our, um, perpendicular constraint there and go ahead and go back and finish our profile. So we should have a basic sketch like this, and I make sure those constraints are in. If this line is cricket, you can just go ahead and add a horizontal constraint. Um, but this looks good. So now we're ready to put in our dimension, so I'll just hit D for Dimension. We're gonna make this 1 10.8 and will make this line 9.5. We'll set. This one is 18 and I'm gonna make this 2.5 and that's that's about it for the overall dimensions. The next thing that I'm going to do is create a circle. We're basically going to create that groove in here. Um, that's gonna bump out. So this part here, So to do that, I'm just gonna go ahead and, uh, put a circle, and I'm gonna I'm just gonna put it anywhere in the middle for now, and I'll give this a dimension of two millimeters. So it's gonna be a little bit smaller than the circle we made in our other component. Um, so we're at two millimeters as the diameter, and we'll go ahead and dimension this from the bottom here to be. Make sure you get this up down dimension and will make that 4.5 millimeters. And I'm gonna dimension this center from this line. So hit the for dimension. Click both, and I'm gonna go 0.4 millimeters. No, I did that just because I wanted this to be offset in a little bit. I don't want I didn't want to put this ride in the circle cause I just want this much of it to really extrude out. So next I just had tea for trim and just trim this part of the start, believing me with just this ark. Okay, so that looks like everything. So now we're ready to revolve this to get our shape. So I'm gonna go ahead and click on stop sketch, and we'll go ahead and choose Creates revolve. I'll choose this profile. Select on axis and shoes are Z axis here, and I'm gonna for angle. I'm just gonna go to full, and that's gonna give me a whole 3 60 degrees. Uh, nobody and click, OK. 14. 14 Bottom Bumpouts: so there's, Ah, rough shape so far. That's our revolve. Or you can see our battery. Um is right there on the top and I'm gonna go ahead and untangle that. I I can see that, you know, it's it's positioned Fine. So I don't need to see that reference anymore. And next, I'm gonna go ahead and grab that the ark and revolve that as well. Now you go back to my other model, so I only want this to go part of the way. I'm not gonna want a full rotation. So to do that and come back and I'm gonna show sketches because sometimes after you create a body for some reason sketches will your sketch willen toggle. So let's turn that back on so we can see that sketch and I'm going to zoom in so I can see that arc and gonna go to create and choose resolve again. Select just that profile this time. And I'm gonna choose my access as the blue access again. And this time, instead of full, I'm gonna change this to angle. And I only want this to be 30. The Greaves and I'm gonna keep it symmetric or if it's yours, a sets of one side, just make sure you change it to symmetric. And that way it gives me 30 degrees on either side and would have the operation as joined and then click. OK, so you should have this shape right now. Okay, So next they'll go ahead and fill it this. So I'm gonna click out for Philip. I'm gonna click on this edge, and we'll also do the other side as well. So quick on this edge here. And let's give this a fill it of, um, we'll say about 10 or so. Just a nice ah, big fill it to give it a really nice transition there. So go ahead and enter. 10 had okay or click answer. And there we go. So that's that's our shape. Whether fill it and the reason for the fill, it will go back to the other drawing and show you. So ah, well, go ahead and activate that top part. So if we look under here when it hits this part, we want that fill it just to give us sort of a smooth, um, smooth curve there. Otherwise, um, you know, it would just be hard to turn if we just have Ah, just a straight edge of there were just kind of bump against this. So you go back to our current drawing. So that's the reason why we did that. And next we'll go ahead and mirror this, so we want to mirror it to the other side. I don't need to see sketches. Um, so I'm gonna turn that off and to mirror this I'm just gonna go to create mirror and I'm going to select features for my pattern type and just select my features for my timeline. So I'm gonna want that revolve that we did, and you'll see it highlight here and also the Philip. And for my mirror plane, I'll go ahead and select this plane here that z x or that Green Plains. And once I click on the plane, you'll see sort of a shadowy image here showing what that's going to look like. That's what I want. So I'm going to click, OK, and there's my mirror, So OK, next, we'll go ahead and create this heart. Let's go back here. Basically, this a bump out over here. This is the part where once we rotate. It's gonna block the led, um, that leg of the led preventing that circuit. Ah, from happening. So that's what will actually turn off the allergy once this part is twisted to the other side. Um, so we'll go ahead and model that. 15. 15 Top Sketch & Circular Pattern: so to do that, we'll go ahead and create a sketch on top of that surface, and I'm gonna choose my offset tool here. So grab, offset. I'm gonna click on the outer perimeter, and I'm gonna offset this and Ah, negative. Um, 0.4 millimeters, and I'm going to do another offsets. We're just gonna right click and repeat, offset. Select that same edge. And this time I'm gonna come in. Um, I'm gonna do a negative 1.2 notice. It's negative as I go win. And then it's positive as I go out. If yours is Ah, if you're seeing an opposite results, for example, positive. When you go into negative when you go out, just make sure to enter that value. For example, if I do a positive number here, if I do just the 1.2 you know it's gonna go ahead and make that offset outside of that circle. So I'm gonna hit controls because that's not what I want. And redo that and let's go in negative 1.2. Okay, so now I'm gonna go ahead and create, um, some lines here to give me the extrusion I want s so I'm gonna have l for line start at the origin, and I'm just gonna go out to this edge here and I'll create another line again. Don't worry about the angle. Just get something like this and I'm gonna go ahead and enter a dimension, so I'm gonna d for Dimension. Oh, actually, I'm gonna need a mirror lying here in the middle, so let's head l for line will start and go straight out. Make sure you get that horizontal constraint there and ah, quick on the check Mark. And we're gonna go ahead and turn this line to a construction lines so that selected and had X and I'm gonna hit d for Dimension and Dimension. This line from this, um, Maryland that I created and click again to set the degree. And we'll have this be the same as this here of that revolved that we made. So we'll have to make that 30 degrees hit enter now instead of mirroring this on that side . Um, I'm just gonna go ahead and choose to do a symmetry constraints. So we're gonna grab symmetry here from Mars. Catch palate. The way the symmetry constraint works as well quick ones on our line. Um, and then click on our other line that we want to be symmetric. And in our third click is the line that we wanted to be symmetric about. So click on that and this line will automatically snap to be whatever angle this is. So that looks good. I'm gonna go ahead and click on Stop sketch again. Our sketch disappeared. Sort of Tackle that back on. And I'm just gonna grab this middle profile here, hit he for extrude, and we're gonna go ahead and extrude ist just two millimeters and click, OK, and I'm gonna grab our Philip Tool. Um, again, I'm just gonna come title sketch. I'll need to see it anymore. So f for Philip. I'm gonna choose this edge here. I'm gonna fill it. This just one millimeter. Fill it and I fulfill it again. And this time I'm gonna choose the side, the center in this side as well. So you'll have those three selections and let's go ahead and give this a fillip of three. Actually, we'll do two millimeters and I didn't click. OK, so that looks good on one more thing to do is to now get work on the bottom to get this shape here where we have, you know, this this sort of ah thumbscrews shape which makes it easy to just be able to grab in turn . So Oh, to do that, we're simply going to go ahead and create another sketch. So when we'll do it on this surface this time, so just orbit to the back and go ahead and just create a circle just on top here somewhere , I'm going to give this a diameter of 10 millimeters and gonna go ahead and positioned this , um, or constrain it so that it's ah lacked here as up and down or a vertical constraints. So I'm gonna grab that horizontal slash vertical constraint. Click once on my center, click on that midpoint. So that's constrained vertically. Could move it up and down. Hit, differ dimension. Well, the mention this from the sensor. Um, we'll say sometimes you have to click this if it's not working. Hit escape. Sometimes I'm the mentioned toe, you know, work right away. So hit escape will try it again. Center There we go. We'll make this 18. So next we will extrude this out so now I can click on Stop sketch. Well, bring back our sketch. You for extreme. Grab this, pull it out for distance. I'm just gonna go all and click, OK? And we're gonna do a fill it, um, and thes edges here. So click here in here. I'll give this affiliative three click. OK? And let's go ahead now and creates a circular pattern so we'll go to creep eight pattern circular pattern. I'm gonna choose features on their pattern type, and that surprised my objects. I'm gonna select that extrusion plus that fill it from our timeline and as the access. I'm just gonna select that perimeter, have that circle, and I'm gonna enter quantity of six and click. OK, and there's our pattern. So remember, we can always go back in my out of five years in our timeline. So, um, let's say, you know, look at thes and we decided You know what? This is just a little too deep of a cut. Let's go back to our sketch and change that. So I'm gonna go to our timeline. This is that's catch remade. And so, instead of 18 let's pull this out a little more. Let's make this 20 millimeters and we'll click on stop sketch and noticed that they all updated now. So we have a little more distance between, um this edge and this curve here. So, um, we can also do the same thing with that. Fill it. We can go back in the men that So if you wanted more of a Philip there, let's say six millimeter. Fill it to give it more of, ah, slight transition. Click. OK, you know, that automatically changes the entire, um, circular pattern there. So great future toe Have I'm gonna hit control Z to go back to our previous fill it. So that's it that concludes this. Ah, bottom part of our component. We're not ready to go ahead and make our top cover. 16. 16 Section Analysis: Let's take a minute to just review everything we've designed so far and just take a look and see how everything is going to fit together. So what I will do is I'll activate the top of our browser here, so I'm just gonna quick on that circle, and that's going to activate everything we can see here. We have our full time line, and I can go ahead and just activate each component so that they're all visible so well. Actually, we'll start with our battery, and below that we have that bottom part, and then we have our top part eso before we model the cover. Let's just take a look. See what we have so you can hit Shift N that's end for Neptune, and that just automatically assigns colors to your different components. So it makes it easy to distinguish so you can see all the different colors we have here, and we want to take a look at the inside. So let's create a section analysis, so we'll go to inspect section analysis and will turn on our origin planes and we can now see or we can see our planes and we can choose which one we want to view. So if I click on this plane here, this, um, z X, you know, it goes ahead and gives us the option to weaken. Move this arrow forwards or backwards to just go ahead and take a look inside our models. So, um, we'll go ahead and to set it to the middle there and click OK, and I'll on title or origin here. So notice what happened. We have a new box here called analysis, and if we expand that, you know, we can turn that light bulb on or off, or the top one on or off. So, um, that will always stay there. And we can also create more section analysis, and they would all be populated under here. So you know, there's one analysis. Let's create another one, actually, So we'll go to inspect again into section analysis, turn on our origin this time. Let's let's look at it from the other directions. So we'll choose that perpendicular plane and we'll just click, OK? And that'll give us a view from this direction. I'll go ahead and untangle origin. So one of the things I can see here is, um I can see how everything lines up on the inside. So I have that half a millimeter gap from the top. But I noticed a problem area here. I can see that this bump out is not quite lining up with that groove there. So let's fix that to do that, you know that I'm gonna have to go into that bottom component and make that change. So let's go ahead and activate that component. You know, it kind of be a pain. I'm not. I'm not sure which sketch it is here. And plus, you always want to go inside that you're component when you do start editing. So let's activate bottom. And now I get a much more condensed timeline. And I know that's that first sketch I made because I made that sketch and I revolved it. So I'm gonna double quick on that first sketch. And so here is the issue, right? It's this the mention between the bottom part here to that circle we made. So it was originally 4.5 millimeters. I'm gonna double click that and just let's change it to four millimeters. So that's gonna bring it down a little bit, and then I'm gonna click, Stop, sketch, and I'll go ahead and activate everything again. Ah, and you can see right there that, you know, that looks like that did the trick. It's now aligned, and so that looks like that's gonna that's gonna work out. Fine. So I'm gonna turn off analysis now, and now we can go ahead and let's go ahead and model the cover. 17. 17 Sketch & Extrude: all the cover. Okay, let's go ahead and model to cover. So to do that, we'll start with a new component. So we will right click new component, and we'll go ahead and rename that to cover. I click on a white space and it should be active eso right now I don't need to see bottom and I don't need to see the battery. Um, I'll just leave the top part visible with our cover being active. So here's our component, um, our top component, which is not active, but because it's visible, it'll appear transparent, and we can also get some information out of here. So if I click on this edge, I can see that it's ah radius of 13 millimeters. So we'll remember that as we model the cover. So we'll start by creating a sketch. Got a sketch, creates catch. I'm gonna choose the top of that component so you'll see it light up. Be careful in your selection here, making sure you're actually selecting that top surface, and we can start drawing on the circle now. I don't need to see it anymore, so I'm just gonna toggle it now I'm gonna hit. See for circle start at the center. And since that, ah, top component was 13 millimeters and radius, which gives us a day habit of 26 millimeters. I'm gonna make this 260.3 millimeters bigger, so I'm going to do 26.3, which gives it a little bigger because this covers gonna slide on top of that components. So I'm gonna need some room here. Otherwise, if I make a both the same size, it just won't fit. So next I'm gonna offset it to give it a thickness. So I'll go ahead and shoes offset and offset the 0.5 millimeters. And I'm gonna need a center circle here for the led to be able to slap through. And I'm just going to make this seven millimeters. Okay, I'm going to stop sketch Select. Are you for extrude? I'm going to select this profile. Um, because I selected that component. These reference sketches came through, which, you know, I didn't really want, but that's OK. We'll work with it. I'm just make sure you select all of these as well, and we'll also select this profile so everything is selected. I'm gonna go ahead and give this a thickness of two millimeters. Actually, we're gonna do one millimeter and hit. Answer. Okay, Now we can go ahead and extrude the edges down. So to do that, I'm going to reveal our sketches are our sketch. And so going to go ahead and take that, um, that perimeter there that we made that offset he for extrude We're going to click on that. And which way do we want to go? So I'm gonna Let's toggle are other components on, so we kind of see a visual reference here. Okay, So I'm gonna take this and bring it down, and I want this to go to the bottom of this part of the top of this part here. So that's our bottom component. I'm gonna go ahead and choose, uh, distance I'm gonna go to object. And for my object, they see how it's highlighted in blue. I'm gonna select that surface, and that will bring a straight down. I'm gonna keep it joined and then click. Ok, All right. So I don't need to see these components anymore, So I'm gonna go ahead and untangle then and untitled sketch. And so now we have our part 18. 18 Increase Radius: After printing and assembling a few of these, I found that the cover was just a little too snug in trying to get it to fit on this top component. Um, I was able to get it on, but it wasn't without a lot of effort. So to make the assembly a little bit easier, we're gonna go ahead and increase the diameter of this cover. So right now, um, something to keep in mind of. When you click on a circle and you're on the model environment, it will give you it in radius form. Um, And when we go into the sketch environment, it gives it to you in diameter form. So right now, we see that the radius is 13.15 so that's gonna be a diameter of 26.3. So we'll go back in and amend that, And that's just something you deal with when you're prototyping for three D printing. It's just constant printing and coming back and tweaking s. So this is what the process really looks like. So we'll go ahead and activate the cover component, and I'm gonna untie, go this top components, and we'll go into that first sketch something a double click and there's our diameter of 26.3. I'm gonna go ahead and change that to a 26.5 click. Enter. This offset of 0.5 was based off of that diameter, so that's automatically going to update. And so all we have to do is just click on Stop sketch. And if we now measure that inside the amateur, remember the Radius Waas a 13.15? It's not 13.25 giving us a diameter of 26.5. So that should work. Ah, better. And remember that different printers have different tolerances. So start with this value. See if it works for your printer. If not, you may have to tweak it a little bit, um, depending and ah, you know the prince or maybe even the filament that you're using. 19. 19 Locking key: next, we're going to create a little circular extrusion from this inside surface here, which is really just going to serve as a sort of locking key so that when we fit the cover and top of our other component, it'll lock it into place and I'll show you what I mean. They'll go back to our finished model here and you'll see if I go ahead and remove top. I'm just gonna activate cover. It's basically going to be this part here, so we'll make an extrusion like that that's going to go ahead and mate with a similar one sort of the female version of that Ah, on our top component. That way, when we slide it in, it'll lock into place. And then when we rotate that bottom part, it'll actually you know, this part will all hold in one piece. Otherwise the cover would just spin around. I mean, we can glue it in place, but this is just something to you know, have so we don't have to use glue, and it'll just lock it in there. So Okay, back to our current design will do this by creating a sketch on this surface. So I'm gonna go to creates catch me to select that surface. Now I want to make sure I'm facing the right way. So let's just go ahead and toggle that top components on. And basically, I want to be opposite of where this opening is here. So I'm gonna model it right on top over here. So now that I see that I can untangle top and I'm gonna go ahead and hit, see for circle. I'm gonna set the circle right on that inner offset line And give this a the mention of 1.8 millimeters in diameter. I'm gonna go ahead and set a vertical constraint. I'm gonna graham that midpoint of that circle and constrain into my origin, and I can hit Stop sketch. Okay, so I'm gonna title sketch back on, and I wouldn't want to select this inside profile here, so I'm gonna get you for extrude Select just that profile. If you're having a hard time selecting it, just you can either click and hold or just, um, untitled the bodies and get that selection. So we're gonna go ahead and grab that era Bring get up. I'm just gonna go five millimeters and hit. Enter 20. 20 On Off Indicators: next, we'll go ahead and sketch some visual representations that will tell us whether the switch is turned on or off. And so I'll show you what I mean. So basically, it's just going to be, you know, the normal zero or one that you see telling you whether something is on or off. And to do that, we're just going to use a circle in a rectangle or more specifically in the lips in a rectangle instead of actually putting in text. So let's go ahead and create a sketch right on top of our surface here. And the one thing we're gonna want to verify is again to make sure we're drawing in the right orientation. So let's bring back our top components, and we want to be drawing on the same side. Ah, as this opening here. So let's go ahead and flip this. I'm gonna go ahead and used these arrows here, have my view Cube to turn this around enough. I turn it this way. I noticed that this is a bottom here. That's where my opening its So I'm going to draw on this side, Okay, so we'll start. Um, just needs a rectangle for the one which is going to represent the on position. And basically, that works because when the switch is turned this way, it's going to push the contacts here. This is where the led context is going to be, and that's gonna close our circuit turning on the led. So we know that this is gonna be are on position so it will create a center rectangle. So we'll go to rectangle sensor rectangle and I'm just gonna create it. Um, just somewhere here right now. And we'll give this a dimension of one by three and hit enter and then we'll go ahead and grab an ellipse. So go to sketch a lips and to draw the lips wolf click left once for our sensor, go up for our radius and click again. And in our third click is going to be that bulge. Just go ahead and make a similar lips, and then we'll come back and enter the dimensions So we'll hit D for Dimension. That vertical he is going to be three millimeters and the horizontal will make that 2.5. Okay, so now let's go ahead and position these. So I'm going to draw a center line from the origin straight down, and we're gonna turn that into a construction line by hitting X. And I'm gonna set a distance. Um, actually, it's moving into place for us to just Teoh. I was gonna drag it to roughly get it to where I, you know, I wanted to be, which is I'll set it somewhere around here. Now I'm gonna hit D for Dimension, and I'm gonna dimension that he lips from this origin and sure, let's try that. We'll do nine millimeters looks good. And let's also do a height dimension. So click do the same thing. Um, but this time will come up in this direction and let's make that five. Okay, so that looks like a good spot for it. Um, next will go ahead and set a a symmetry between these two. So we're gonna grab on symmetry. I'm going to click on the lips. I'm also going to click on that center rectangle and in my symmetry line is going to be my construction line I made. And that's gonna go ahead and snap this so that it's lined up with our ellipse. So that looks good. Someone to click stops catch. I'm going to tackle sketches back on and let's go ahead and extrude those through. So I'm gonna hit he for extrude and click this in this surface and we're gonna go straight down. I'm just gonna choose distance as what We don't want to choose. All OK, so here's a problem. It's actually going through our component. Um, which is okay, all we have to do is just deactivate it. Um, that's the repairs. If we go in there, objects to cut, let's try. I think it's is just kind of left over, so let's just do it one more time just to make sure we're not cutting anything else. So it's on first will untangle that component that I had on because we definitely don't want toe cut through that So e again for extrude 12 Gonna go at distance, I'm gonna choose all. Actually, we're going to make sure we drag it down first. So we get cut and then we'll choose All Okay, that looks good. Then we can verify if we go in there, objects to cut its only cutting the cover. Okay, so that's it for the cover. The next thing we're going to do is we have to go back to that top component to create sort of that the inset for this, where this is going to slot into. 21. 21 Slot: next, we'll go ahead and create the slat where this extrusion was slight into on our top component. So we'll go ahead and activate the top component who make it visible and will untangle have a cover so we don't see it. Okay, so we'll go ahead and sketch on this top surface, and basically, that extrusion is gonna be opposite this opening. So we're gonna want to make it on the top here. So let's go ahead and create a sketch on this surface. And be careful, cause sometimes it has a tendency to flip on you. So after you create yours, catch, make sure you double check it. Um, so as we can see, it did flip. So I'm going to rotate this using our few cube here. Enough. I look at it. Here's our opening. So I'm gonna want a sketch up here. So to go ahead and create, um, the sketch, I'm just gonna make a circle, and I'll make it up top here somewhere. And just go ahead and give this a diameter of ah, well, due to 0.1 millimeters because our other extrusion was 1.8 millimeters in diameter. We're gonna want to go a little bit bigger around this. So, uh, a 0.3 millimeter tolerance will be Will give us a nice a nice fit. So I'm going to do 2.1 millimeters head enter, and then we'll go ahead and constrain this. It's who are, well, grab vertical constraint. I grab our circle, grab and constrain its who I origin. And then we'll also do a coincident constraint from her circle. So our perimeter that'll lock it in place. So now I can go ahead and click on stops. Catch. Grab this portion. Um, actually hit the for extrude grabbed that profile, and we'll bring this down. Also. Negative five millimeters. Okay. And that sets are extrusion there. So let's go ahead and make everything visible here and by activating all the components. And so if a go ahead and Targo by the cover on, So let's take a look under it here. I'm gonna go ahead and untitled the top. We should see. That's not right. There 22. 22 Arrow Indicator to Bottom Component: the final thing we're going to do is carve in a little notch on our bottom component s so that when we wrote hate that bottom part, it'll point to either being on or being off. So let's go ahead and activate that bottom component will make it visible and will entitle cover next. We'll go ahead and create us catch right on this surface. And I wanted to be on this particular arm here, so it's going to be directly in front of this extrusion here. So let's go ahead and click on the top view on the View Cube. And we're gonna create that notch by basically just sketching a triangle here. So we'll create that triangle by using our polygon, uh, tool here So we'll go ahead and go Polygon. For some reason, it's jumping on me, Probably gone circumscribed polygon and I created on the side and I'm moving into place here so we'll set click ones to get the shape and and I'm gonna hit tab and change this from 6 to 3 and hit tab again. That brings us back to the dimension, and I can rotate it or set in the mention I'm just gonna eyeball it for now. And I want the pointy side or one of the point decides to point up are close to up for announce. So I'm just gonna do that and just collect it, get something basic. Um, Then I'm going to set some constraints, so we'll grab the horizontal slash vertical constraint and constraint that to our midpoint there. Um, next, I can go ahead and let's see. Let's set. Ah, horizontal constraint on this bottom here. So we'll go to horizontal again and click on that bottom and then weaken dimension this from the top. So we'll say, uh, let's try 15. That looks pretty good. Um, the next hole actually doing the mentioned from here to the top to set that radius. Uh, make this a little bit smaller. 1 to 1.5. Um, actually, get away with two millimeters here, and that looks good. So I'm gonna go ahead and click. Stop sketch e for extreme. Select that profile, and I'm gonna drop it. Just 0.6 millimeters. I'm gonna have to do a negative there. So negative 0.6 and that'll give me a little slot on going inwards. so now we'll be able to once this has turned at this little triangle point to it being either on or off. 23. 23 Top Fillet: In some instances when printing the top part, I came upon this problem where instead of the filament taking the regular path of that contoured shape all the way around, it looks like it failed to adhere. And instead, um, ended up with this sort of bridging effect. Now, this didn't happen with every print, and it only seems to happen with certain filaments. And it happened, and only in cases where I printed all three parts together. And another thing is that I seem to solve this problem if I just increase the temperature. So I believe increasing the temperature allowed it to be able to, um, have sort of, ah, better adherents, I would say to the previous layers. But the overall problem, I'm pretty sure has to do with that overhang. So to completely prevent this from happening, we're gonna go back into that sketch and let's see how we can fix it. So let's go into fusion. And I've got my, uh, top part of my browser here activated. So have all the components active. I'm gonna go ahead and hit shift and again, just to, um, go ahead and assign its colors. So each component gets its own color now because I close and opened up the program. Um A It's now we're just going to go ahead and in a sign, just random colors so the colors won't match what I used last time. But don't let that throw you off. It just assigns random colors. Okay, so let's go ahead and activate that top component, and I'm gonna go ahead and untangle the rest of the parts and let's take a look at this. So here's the overhang that we're dealing with its this part here. And let's go ahead and turn on that section analysis. We can see it better. So it's basically this here with some filaments. Um, this could be tough, a tough overhang for it to be able to handle. Um, like I said, you can probably solve it. We're just increasing the temperature. Um, that seemed to help its take a little better. But to prevent this from, you know, just being an issue, we're gonna go ahead and just add a fill it there. So let me turn off analysis, and I'm just gonna go ahead and click on that top ege and type F for fill it, and we'll give this a one millimetre Philip and head in term, and that will go ahead on soft. That problem. You see how now I'll turn analysis back on. And so now we have a smoother transition here, um, to that part and we won't have to worry about, You know, that's deep overhang here. So that's an easy fix. And again, I wanted to leave that and just to give you another example of how to go back in just, uh, to each component in tweak your your drugs. Um so that said, I think that's the final tweak we're going to do, and we're all set to three d print this. 24. 24 Extrusion Width: This is a good spot to point out an important concept to understand when you're designing for three D printing and has specifically to do with the wall thickness of our prints. So right now I have the cover component activated, and if I go into our sketch, we can see that the thickness of that wall is whatever this offset is that we set. So we're looking at 0.5 millimeters. So that's what this thicknesses. Now I'm printing ah, with a 0.4 millimeters nozzle. So I'm not gonna have any issues printing this wall. That nozzle will be able to handle that. Now let's say you're printing with a 0.6 or most more likely a 0.5 millimeter nozzle. Um, you would think that if the wall thicknesses 0.5 millimeter and you're printing with a 0.5 millimeter nozzle, that you would be okay, but you're actually gonna face some problems. Um, are you You're most likely. I should say to face and problems and not not show you why. So right now, I'm gonna go ahead and send this model to our, um three d printing utility. So I'm gonna go make three d print Select the model, and I'm going to choose one of the software here under Prince utility that I have installed . I'm gonna go ahead with custom because I have simplify three D as installed under custom and someone to click. OK, And the reason I'm choosing simplify three days because they have a really nice simulation feature to their software, which is gonna allow me to just easily make my point. So Ah, I see our model is loaded here, and I'm gonna go on their process and look at what my extrude er settings are So like I said, I'm printing with a zero point for a millimeter nozzle, but there's something else to note about that you're gonna have another option that's gonna say what you're extrusion with is I haven't set to auto, and the software automatically sets what it has pre configured. The right setting is for the particular printer, so it has an extra jher with a zero point for eight millimeters. Basically, what it's assuming is that when I laid on that layer of plastic, there's gonna be some expansion there, and it's gonna assume that the plastic is going to come out a little bit wider than what my nozzle diameter is. So at 0.4 millimeter Naz Oh my with is 0.48 But I know that my wall that I designed infusion 3 60 0.5 so it should have no problem being able to print that. And let's see what that looks like. I'm gonna click, OK, I'm gonna go to prepare to print and I'm just going to click on play, and it's going to start simulating what the printer is going to do. So I'm just going to speed this up and we'll see. We'll get through that first layer and then it starts to print that outer wall. So if I zoom in a little bit, um, speeded up a little more, you see that wall being printed? And so if we look closely here, we can see that it's just dropping one perimeter, um, filament across that wall. So it's just that that 11 shell, um and so that works fine, so we can see if I speed this up the rest of the way. I have my model there, Um, and everything is looking good, But let's go ahead and stop this and we'll go ahead and go back to our settings handsome in the exit preview mode and go back to processes. And so what I want to point out is, the important thing that you have to be aware of is that whatever that wall thicknesses, that number has to be bigger than whatever you're extrusion with ISS. So the reason I'm okay is because my wall thicknesses 0.5 millimeters in my extrusion with a 0.48 But let's say, for example, your printing with a 0.5 millimeter nozzle. Now that extrusion with automatically says, Well, that's going to be a 0.6 millimeter extrusion with Okay, so our while we designed remember 0.5 millimeters. So if our extrusion with his 0.6 millimeters ah thick, then there's no way we're gonna be able to print a wall that's Onley 0.5 millimeters. So let's go ahead and simulate that and see what happens. So we'll go to prepare to print and let's go ahead and play that simulation. So again, I'll speed this up and we begin to see that it see how it's Prince. This part? Fine. This is that, um, little cylinder that we modeled because that's thicker than 0.6 millimeters. But everything else it's not gonna print, So that's all we're going to get. So let's all go ahead and exit preview mode. Look back at our settings again. Um, so very important to keep that in mind. Um, so in this case, how would we fix that? Right, if we have a 0.5 millimeter nozzle. Um, like I said, you can always go back and make this smaller. But you have to be careful. Um, because, you know, usually you have this set to a number that gives you the right setting that gives you that perfect extrusion. So you don't always want to tweak this. What you may have to do is go back and change your fusion 3 60 drawing to go ahead and make that wall a thicker. So let's do that and then click. Ok, uh, let's remove that model. Gonna close this out, and so we'll go into fusion and let's go back can modify that sketch now. So we'll go. We're gonna go into that, um, offset here and we're gonna change this. So you may think Okay, I'm gonna go ahead and just make this a 0.6, um millimeters. Because that was our extrusion with with the 0.5 millimeter nozzle. But what I found out is you actually, you can't be the same number. That's also going to give you problems. You have to be a little bit bigger. Um, so let's do 0.61 in this case and click OK, stops catch. Now we'll go ahead and extreme. Go ahead and three d print this So three d print custom. Okay, bring it back into a simplify three D. Let's look at our settings again. I'm gonna make this a 0.5 millimeter nozzle. Our extrusion with is 0.6 minute click. OK? And let's go ahead and simulate that. Oops. Quick play can was get a good angle here. So you can see now that Prince Fine. So we're good to go. Um so just the important thing to remember your with cannot be smaller. Didn't your extrusion with whatever you model that you know, it can't even be the same size That will also give you problems so you're gonna want to make that a little bit bigger. So we went. We model that point. Um, 61 We told it, we're using a 610.5 millimeter nozzle like calculated and extrusion with a 0.6. Um, and so we're good to go. Um, OK, that I just wanted to point that out because, um, you always have to keep that in mind when you're modeling what's going to be the size of the nozzle you're using. So when you do face that problem, you know a way that you can go back and fix it. 25. 25 Assemble All the Parts: an led will have a long and a short leg, the long leg corresponding to the positive side in the short leg. The negative to assembled is we're gonna insert the short leg right through the center hole and will take that long leg and just run it through that channel and bend it to decide. Now we'll go ahead and grab that short leg using appear of needle nose pliers and just go ahead and threaded back through that other hole and then pull it from the other side. So that's nice. And talk next will grab the long leg and we'll go ahead and slide it through the side holes and then do a similar thing. Well, we're just gonna go ahead and threaded back through the hole and then again, pull it tight. You're gonna want to grab a pair of slippers here to go ahead and cut that piece off, and we'll do the same thing with the top. Um, top lead will also go ahead and snip that off next. Right? It was I just grabbed the small little screwdriver, a little flat head and just inserted those leads and to those channels and just flattened it on the bottom. Now, when we print this, the bottom part that lays on the bed usually has a little brim around it. So what I'm doing here is just taking a file on just filing that off, because this is going to be a pretty tight fit once we get that cover on now, to attach the cover were simply gonna align those two slots and then just apply a little bit of pressure and it should snap right into place. Next comes the battery. Now, when you put, replace the battery, make sure to place the negative side up and then just grab the cover assembly and simply line it up. And again, just apply a little bit of force here, and you should hear it snap right into place to turn on our led. All we have to do now is simply rotate it to one side and to turn it off, we rotated to the other side 26. 26 Congratulations: congratulations on completing this course. I want to invite you to visit my website. That's top makes that calm because I'll be putting some additional resource. Is there, for example, have a link to my YouTube channel and also a link to my thing of her space, where you can download all my models for free. Ah, plus, it's gonna be a place where I'll be leaving links for all my future courses. So I do plan to create a much more of these project related courses, and that will be a hub where I'll keep the ball. So all right, hope you enjoyed the course, and I hope to see you on the next course.
