A remix of imitation's extruder, the extruder has been edited to remove some unneeded verticies and shrunk slighly on the Z axis to reduce printing time. This is the extruder body we use on our Mako and X3 printers, and later iterations. As we edit the design, I'll update the files. All Diamond Age Printer parts and customizations are organized in our collection here: http://www.thingiverse.com/DiamondAge/collections/diamond-age-printer
