compact bevel geared extruder for mk8 hobbed filament gear V4 UPDATED 13th July 2015

This is a compact bevel geared extruder that is designed for the small pneumatic fittings available at e3d.

The gear ratio is 2.3:1 which gives more than enough torque even with a smaller NEMA 17's.
It's easy to assemble the only thing I would say is the shaft on the stepper motor needs to be cut down by about 10mm.
