Raspberry Pi B+ bracket for Printrbot Simple Metal

I made one of these great sleeve cases for my Raspberry Pi B+.

I wanted to be able to mount it on my Printrbot Simple Metal, so I started by making a device to attach it easily to the PSM. Using sketchup and a bit of trial and error I came up with a bracket that would clip onto the bottom of the two 12mm Z-axis rods.

The second piece is just a simple saddle clamp for the Pi case. It hangs off the bracket. you may want to print two of the PiClip.stl
