Raspberry Pi 3 (2 and B+) case

Case for Raspberry Pi 3 (2 or B+).

The imported rPi SVG logo from the Wikipedia: http://en.wikipedia.org/wiki/File:Raspberry_Pi_Logo.svg

update_1: I changed the lower_part.stl
I removed the chamfers on bottom part holes, for easier FDM printing.
update_2: Now you can use 4 small screws or nails which are about 1.5 - 2 cm long and the head diameter about 4mm.
update_3: My Pi 3 just arrived and finally tested the model. Simplified the upper part and use 19mm long small screws.
