Raspberry Pi Zero 1/2 snap-cases (slim, GPIO)

Raspberry Zero 2 slim case, that fits in a wallet.
There are snaps around rim and on the 4 pins.
It's low tolerance model, so stick to 0.12 height and 0.24 thickness for parts to fit nicely.

Rpi0 is 5mm in thickest area (3.5mm micro hdmi port + 1.5mm board). In model only additional thickness is two 0.12mm layers on bottom, just to cover pins. So overall thickness of case is around 5.24mm, highly dependable on bed leveling.

I've also added slot for radiator that I had to grind to 1.4mm high to even it with hdmi port, although it might not be necessary, so there is also a 2nd top stl part without it.

Designed for zero 2, but also fits zero 1. However on zero 1, processor is smaller and slightly in different position, so radiator hole won't be completely over it.
