CAD 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.

  • arm-right.stl
  • arm-feather.stl
  • arm-nRF52840.stl
  • LED glasses frame.stl

Slicing Parts

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

CAD Assembly

The Feather is secured to the arm with M2.5 x 6mm screws and hex nuts. The two arms are secured to the frame with M2.5 x 14mm long machine screws and hex nuts. The frame is secured to the LED glasses PCB with M3 x 6mm long screws and hex nuts. The Feather connects to the LED glasses using a 50mm STEMMA QT cable.

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.
