Raspberry Pi Fan Shroud

A shroud for a 30x30x7 fan for the raspberry pi which can be bolted on top of a perforated case.

For printing:
4 walls, no bottom layers, no top layers turns this from a solid object into a fan shroud.

Notes:
There is still an issue where the holes for the screws are not very good looking. But they should bridge fine and the part should end up functional.
