3D Printed 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.

CAD Assembly

The FunHouse is secured to the pcb-mount with M3 screws. The pcb-mount is attached to the frame using M3 screws and hexnuts. The EMC2101 breakout is secured to the pcb-mount with M2.5 screws. The 140mm fan is secured to the back-cover with M4 screws and hex nuts. The back-cover snap fits over the frame. The carbon filter is press fitted into the front-cover. The SGP30 sensor is secured to the center of the sensor-mount using M2.5 screws and hex nuts. The sensor-mount is secured to the front cover using M3 screws and hex nuts. The front-cover snap fits over the frame. 

Slicing Parts

Minimum build volume required 154mm x 154mm. No supports are required. Slice with setting 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

Slicing Fan Grill

The fan grill mesh is created by using the slicing softwares infill pattern. Set the Top/Bottom layers to 0 and choose your preferred infill settings. Use a minimum of 10% infill. Gyroid patter is used in the screenshot.

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.
