3D Printing

Parts List

STL files for 3D printing are oriented to print "as-is" on FDM style machines. Parts are designed to 3D print without any support material. Original design source may be downloaded using the links below.

  • fan-box.stl
  • fan-cover.stl
  • fan-plate.stl
  • back-cover.stl
  • base.stl

CAD Assembly

The 5VDC fan is placed into the fan-box. The back-cover is press fitted onto the fan-box.  The fan-plate is placed over the 5VDC fan. A carbon filter is placed into the fan-cover. The fan-cover snap fit over the fan-box. The base is secured to the fan-box with an M5 x 20mm long screw and hex nut.

Slicing Parts

No supports are required. Slice with settings for PLA material. 

The parts were sliced using CURA using the slice settings below.

  • PLA filament 220c extruder
  • 0.2 layer height
  • 10% gyroid infill
  • 60mm/s print speed
  • 60c heated bed

Design Source Files

The project assembly was designed in Fusion 360. This can be downloaded in different formats like STEP, STL and more. Electronic components like Adafruit's board, displays, connectors and more can be downloaded from the Adafruit CAD parts GitHub Repo.
