Raspberry Pi 4 case with 5015 fan

I had a spare Prusa 5v blower fan and a Raspberry Pi that was getting a little toasty, so I made more work for myself and designed this. Fairly slim case that mounts a 50mm x 15mm blower fan on the top in an exhaust configuration. I also added a lip around the SD card to protect it from any unfortunate accidents. Uses 2x M3 screws to attach the fan to the lid, and 4x M2.5 screws to secure the lid to the base.
