Adafruit Pi Box - Enclosure for Raspberry Pi® Computers with Logo
Derivative of Adafruit's Raspberry Pi Case. As of time I made the original case, Adafruit's SVG did not show the correct dimensions in Inkscape. So I took out some calipers and measured, and resized. May be a TAD bit too large, but the Pi fits well, and does not move too much.
I also added the Raspberry Pi Logo, added some heat venting holes, and added some holes on the top that fits Radioshack 276-150 Perfboards.
