Box Fan High-Pressure Mod – 3D Printable model

Transform your standard box fan into a high-performance airflow machine with this 3D printable High-Pressure Mod! Whether you're building a DIY air filtration system (for wildfire smoke, dust, or allergens), improving workshop ventilation, or just maximizing your fan’s efficiency, this mod significantly enhances airflow and pressure—especially when used with filters.

Key Features:
✔ 8 Easy-to-Print Parts – Designed for quick assembly and compatibility with most 20" box fans .
✔ Optimized Airflow – Reduces air recirculation around fan blades, forcing more air through filters or ducts.
✔ High-Pressure Performance – Ideal for pushing/pulling air through obstructions (HEPA filters, carbon filters, etc.).
✔ 3D Printer Friendly – Works best on SLA/DLP resin printers (for airtight seals) but also printable on FDM/FFF (PLA/PETG recommended).
✔ Scalable Design – Default size fits 20" fans, but adjustable in slicing software for other sizes.

Recommended Printing Settings:
Printer Type: SLA/DLP (resin) preferred for smooth, airtight parts | FDM works (use 100% infill for strength).

Layer Height: 0.05–0.1mm (resin) | 0.15–0.2mm (FDM).

Infill: 100% (solid parts) for rigidity and airtightness.

Supports: Needed for overhangs (auto-generate in slicer).

File Formats Included:
STL, OBJ, STEP (for editing) – Compatible with all major 3D software.

Visual Assembly Guide (PDF) – Step-by-step instructions for installation.

Software Compatibility:
For Printing: Use Chitubox, Lychee Slicer, PrusaSlicer, or Cura.

For Customization: Modify in Fusion 360, Blender, or Tinkercad.

Perfect For:
🔥 DIY Air Purifiers (wildfire smoke, dust, allergies)
🛠 Workshop Dust Collection
💨 HVAC & Ventilation Projects
🌬 High-Pressure Fan Upgrades

Note: This is a digital 3D file set—no physical fan/filters included. Print, assemble, and supercharge your fan’s performance!
