Raspberry Pi Case
I showed a few revisions of my raspberry Pi case previously. The final design was based upon this two part flex box so that the case can be made from just two parts and assembled without any fixings. Ventilation holes were put in the top and the USB, network and SD card are all accessible. The lower bend radius is a little bit tight so you'll need to be careful if you put one together but once it is assembled it's actually very sturdy. (svg here)
