3D printed case for Badger2040
A 3D-printed case has a slot for two CR2032 batteries. Badger 2040 runs on RPi 2040. It is energy efficient, and batteries should last for a long time. Also comes with a battery toggle switch to shut everything down.
The device is approximately 12mm thick, see below. I lost my digital caliper, may replace the side shot later.
Assembly
Steps:
- 3D print top and bottom panels. PLA plastic is good enough.
- Disassemble & attach a 2xCR2032 battery holder https://www.adafruit.com/product/783.
- Assemble the badge, use hot glue whenever applicable
Known bugs
- A 3D model has minor misalignments that I did not bother to fix, e.g. a LED hole is 0.1-0.2mm off to the left.
