Anet A8 mainboard 50mm fan cover

Remix of Leo_N's cover for use with a 50mm fan. The fan comfortably fits inside the cover. TinkerCAD: https://tinkercad.com/things/aWQNySoEhhf

I used M3x20mm screws as that's what I had on hand, clearly they're a bit long, which is why the nuts are on the outside rather than the inside.

Update 2017-01-23: Added version with Leo_N's v1.1 mainboard update. The only difference is the area over the main power connector is opened up. https://tinkercad.com/things/cDZK7KQokH5
