This is just a simple fan cover to help keep schmoo from falling into your rPi case if the fan is facing up. I added the raised rPi logo simply for character.

Added v2 with a thinner base and 0.5mm walls elsewhere. The screws that came w/ my kit were M3 with a 5mm head so I based the cover around that.

Also added the fusion360 file if you want to tweak anything.
