3D Printed Parts

Parts are designed to be 3D printed with FDM based machines. STL files are oriented to print "as is". Machines with dual extrusion or single extrusion setups are listed below with parts name and description. Parts require tight tolerances that might need adjusting slice setting. Reference the suggested settings below.

Parts List

Use the parts list to reference filenames and extruder versions. 

  • ttc-box.stl – cube frame (single extrusion)
  • ttc-box-A.stl – cube frame (dual extrusion)
  • ttc-box-B.stl – clear panels (dual extrusion)
  • ttc-side.stl – 3x quantity symmetrical side panels
  • ttc-top-side.stl – Install NeoPixel to this panel
  • ttc-bot-side.stl – Install to cover to this panel
  • ttc-back-side.stl – Panel with USB port
  • ttc-cover.stl – Install Feather HUZZAH to this panel

Tap Mounting Holes

I used a set of screw taps to create threads in the various mounting holes. This greatly improves fastening screws. of the A mix of metric sizes are used here. M2.5 taps for the various mounts.

Parts Assembly

The Feather is secured to the bottom cover using M2.5 x 8mm flat head machine screws. The bottom cover snap fits onto the bottom of the cube. Several panels are snap fitted into the openings.

CURA Slicing Software

Rotate to orient the cube so the microUSB opening facing the top – This orientation is best for 3D printing support free.


Tool heads equipped for dual extrusion can be setup using the ttc-box-A.stl and ttc-box-B.stl named parts. Use a transparent filament for part B and a darker color for part A.

Design Source Files

The enclosure assembly was designed in Fusion 360. This can be downloaded in different formats like STEP, SAT and more. Electronic components like the board, displays, connectors and more can be downloaded from our Fusion 360 CAD parts github repo.
