Wade's Geared Extruder modified for dual extrusion. This extruder is currently untested, but please try it out and post your results. In the future I would like to use it for printing dissolvable support structures.This is assembled similarly to Wade's Extruder.The screws that apply pressure to the idler are held in place by captive nuts placed in the four top slots.(Two nuts per slot)The extruder is 1.3mm to wide for the carriage, and can be fixed with a file.
