A no-nonsense clam shell style Atomic Pi case in two flavors. 1.5mm walls and 0.75mm walls (half thickness). Its vented too!

Designed for use with the official "DLI Flush Mount Baby Breakout Board" addon which adds a barrel jack, two LEDs and some GPIO pinout headers. This breakout board is NOT required though. You can glue in your own connector and LEDs.

I received mine through this kit: https://www.amazon.com/DLI-Atomic-Pi-Peripheral-Camera/dp/B07DVYDDV8/

I made a case that supports SATA SSDs too: https://www.thingiverse.com/thing:3850448

Update (23 March 23):
Fusion360 and STEP source files included (these match the SATA drive revision in their supplied state).
