Raspberry Pi 7" Touch - Acrylic Case

This case is based on the really nice lasercut case by Sparkovsky.

Whats's different to the original:
- every part is now 3mm thick material
- removed the camera mount and replaced it with hexagons
- every screw is now 3mm

I recommend M3x12 screws, max screw length is 15mm. Don't even try 16mm long screws.
