This is basically a giant remix of Jon Lawrence's Printrbot Simple parts to become something more like a Printrbot Plus.

I decided to add all of the files to a .zip folder instead of uploading every STL as that would take forever. The JonbotComplete.stl is for reference only.

Update - 4/28/2015 - Added single extruder/hotend mount.
