I made this for a new Raspberry Pi 3* (upgraded my Octoprint server), but it should also work with a Pi 2 and Pi B+ too. It has a larger cutout for the microSD card slot which isn't spring loaded on the Pi 3. Octoprint on the new Pi 3 is much more responsive, but I don't know how much of it is the faster Pi or the updated OctoPi image which no longer runs the GUI.

The case prints vertically in one piece without support, and needs to be bent slightly to slide over the Raspberry Pi.
