This model is build from the ground up to house a slimagotchi with PiSugar3 battery and Waveshare V4 screen.

All ports and the two buttons of the PiSugar are accessable. The back of the case has a locking dovetail joint.

It was modeled to be printed without supports using overhangs. If you want cleaner surfaces around the ports, feel free to add supports yourself.
