Raspberry Pi B+/2 B 30mm Fan Top with vents.

Remix of Jayftee's Raspberry Pi B+/2 B case for a 30mm fan (YX2500). printed at 101% scale (as other people have for his other models) and fits perfectly.
Includes a small hole near the screws for wires to go through if the fan is mounted on the outside. Can be mounted on the inside.
