Latest Pi case with stand and camera housing for Pi 2, 3 and B+ - http://www.thingiverse.com/thing:1771908
Update 16 May, 2014
Since I usually orient the case with the USB ports at the top, I rotated the biohazard symbol 180 degrees.
Another Raspberry Pi case. Biohazard symbol, just because. Screwed together because my prints didn't seem to want to just snap together.
The LED window is a tube that goes down almost to the PC board so you can see the lights reflecting off the walls from almost any angle.
Printed at .33 layer height with a .5 nozzle. The screw hole for the cover doesn't go all the way through to provide print support, so you'll have to drill it out. 2 x 14 mm self tapping screws were used.
