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.

Mini or Small 8x8

The two versions feature identical file names. Choose the version you want to build.

Fusion 360 Download

The links below will launch the CAD in a browser. You can interact with the model and download files using links in the top right.

CAD Assembly

The Feather Sense, slide switch and battery are housed in the bottom base cover using tabs and built-in standoffs. The 3x spindles are secured to the base covers using 6x M3 screws. The top and bottom base feature snap fit covers.

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

Slice with Brim

Adding a brim can help improve adhesion to the build plate. Brim adds a single layer around the base of the model. Models with small surface area touching the bed is prune to peel off especially with tall objects. Use a brim with a 3mm width when slicing the three spindles.

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.
