Raspberry pi B+ fan case.

Update: now with 40mm fan version. This one is much cleaner.
A work in progress. I love overclocking my pi but there aren't many cases that incorporate a fan. My favorite case I've found so far is jayftee's safe and secure case, but I wanted to add a fan. MaximSachs's case looked ideal but wasn't for a B+. I whipped up my first draft of the two in sketchup, but it kept screwing up the mesh. I was able to create a successful prototype but made a few discoveries along the way, and I hope to make some changes in a second version.
So this is what I have so far. The geometry is a bit off but it fits. Also, this is for a 50mm fan. My second version will have a 40mm fan and holes in the case for a fan cable. I'm just throwing this out there as I hope it will inspire someone else with better modeling skills to create something a bit more polished.
