Feeling guilty for abbandoning my previous case project ( http://www.thingiverse.com/thing:398399 ), i came up with this refactored one wich should be a snap-fit ease mechanism both for the raspberry itself (with space between the bottom of the board and the case for cooling purposes) and the top part.

The case itself exposes all the ports of the raspberryPi and there are 2 hollows for a GPIO ribbon cable and a camera cable.

There are also a variant of the top with holes for better cooling and a variant of the bottom with VESA 75/100 mounting

I attach the blender source wich has all the port models ready for boolean differences (or union for the VESA addon) to be applied so everyone can choose wich port expose with the case. Please note that the measure unit in the blend project is set in meters, but when imported in slicing softwares it appears to be in millimeters (the right scale)
