In this tutorial I chat about my design for housing the PropMaker FeatherWing and Feather M4 Express in this prop inspired by the TVA Time stick from the Disney+ show Loki. I really like using threads to make this type of assemblies easy to take apart and put back together. By making the pommel removable from the handle, the USB port from the microcontroller becomes easily accessible. I managed to design the PCB holder so it doesn’t require any supports when 3D printing.
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:
- 3W LED Holder
- 7x Diffuser
- Feather Holder
- Pole Lower
- Pole Upper
- Speaker Holder
Download a PDF of the designs technical drawing. The guard thread-size can be used to design an adapter for making custom diffusers and light fixtures.
The parts require a 3D printer with a minimum build volume.
- 150mm (X) x 150mm (Y) x 140mm (Z)
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
The 7x diffuser tubes are printed using clear translucent PLA filament. Use 0% infill to make the model hollow. Using a brim can help with good bed adhesion. Printing a single diffuser at a time is suggested for best print quality.
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.
