This is a case for my game console. It hosts a Raspberry Pi 3, a small NeoPixel LED ring and a 9 pin Sub-D connector.
The lid is screwed using M4 bolts that are tightened using screw-in nuts (M4 screw-in nuts fit in the 4 corner holes of the case).
The Sub-D connector is fitted using M3 bolts+nuts.
The Raspberry Pi is mounted using M3 screws. The holes for that were drilled after printing. I glued 4 rubber feet under the console.
Printing: no supports were used at all. The dome was printed using neutral colored PLA.
The text "Fit Console" can be changed within the Openscad file.
