Holds a RPi on to Printrbot Simple Metal RPi Camera Bed Mount designed by Jerware.
This only holds a RPi in a Vilros RPi case.
However, feel free to modify this in anyway to hold yours!
**Check out this RPi case that mounts to the camera mount!!!! http://www.thingiverse.com/thing:673133
Print both the holder and the small sleeve.
Place the holder on the Camera mount, and use a screw and nut leftover from your printrbot and the sleeve to mount the holder to the vertical hole in the camera mount.
