This extruder is a revision of : http://www.thingiverse.com/thing:13727.
The drive lever hole is elongated to keep the threads of the 3mm socketcap bolt from jamming the lever. Both parts have been thickened in the revised areas to prevent warping. The extruder drive in the picture was printed in ABS at 0.1mm layer height on a heated bed. It is mounted on a Hadron Bot frame and has worked reliably with this re-design. This drive uses the makerbot mk7 filament feed gear.
