Caution, this is experimental.
Not sure if the Nema17 will have enough torque to push 3mm PLA into the hotend but I'm going to have a go.
Influenced by a number of very good designs already out there this has the mounting base integral to allow it to directly replace the existing Wade type extruder.
Uses a 688AZ bearing which measures 16mm OD, 8mm shaft and is 5mm wide.
Nema17 motor, the big one.
