Compact Bowden Extruder Drive for One/Two Up (modified)

thingiverse

This is an improved version of MacAttak's remixed extruder driver. I have included my own .scad file which will make it simpler to understand what was modified. Please see MacAttak's revised rendition of this item for the original .scad file that I built from. I kept the idler lever intact so you can use the original STL file that came with it. The base, on the other hand, underwent a complete transformation to fit a 1/8 NPT push-fit bowden connector, as well as easy mounting onto the top plate of the One/Two Up. One thing worth noting is that when attaching this driver to the top plate of the One/Two Up, move it about three millimeters towards the outside before drilling any holes in order to avoid a lost 30mm of print height, unless you plan on shaving off two to three millimeters from the left side of your MDF where the z-screw nut resides - I may choose this route instead. For building and assembling this remixed driver: To complete this build you will need to get two additional 4-millimeter bolts, each with nuts about thirteen to fifteen millimeters long. These bolts should then be used to bolt this extruder directly onto the top plate of your One/Two Up.
