Raspberry Pi Zero 2W case with heat sink and GPIO cutout

The top/bottom layers are only 0.4mm thick, but the rigidity is not compromised thanks to the ribs. The whole thing can be assembled with four M2.5x8 screws.

This model is designed to be printed with a 0.8mm wall thickness (0.4mm linewidth, 2 walls) and a 0.2mm layer height.
