Mounting Plate: J Head Lite and Printrbot V2.1

This plate is a duplicate of the one that comes with the newer Printrbots with the holes for the Al extruder. However, it has a slot in it for the J-head lite instead of the Ubis hole.

You may have to fiddle with the size of "box" and "bolt" in the source depending on how accurate your printer makes holes.

This would be a good starting point if you need to make a similar adapter for another head.
