Printrbot Extruder stl files
thingiverse
These are the stl files of the Printrbot Extruder from Brook Drumms dxf files on Thingiverse (http://www.thingiverse.com/thing:31267). I made them 5mm thick, and even though the original laser cut wooden parts seem to be slightly thicker, they work great! Just make sure that your hobbed bolt stays centered!
