Raspberry Pi B+ Sleeve Case Stand
I needed a decent stand for my Octoprint RasPi and I love the sleeve case designs. Didn't take me too long to design this in TinkerCad, but the good thing about this stand is that it fits nice and snug without obscuring the Micro USB on the side too much.
The case I used is based off of Walter's design (http://www.thingiverse.com/thing:604915), so chances are there's plenty more out there that this will work with.
