Zmorph clip-on extruder (new version, September 2013)

thingiverse

This extruder optimizes travel on the X and Z axes by placing the motor at its lowest point on the carriage, perpendicular to the X-axis. It's secured with two screws tightened from above, while the body attaches to the carriage using just one screw for quick detachment/attachment. The design ensures rigidity without wobble, even at high speeds. Additionally, the carriage is compatible with the zMorph DREMEL mount, transforming your printer into a milling machine. For assembly, print extruder_body.stl and carriage.stl, then attach the carriage to your X-axis using 4 LM8UU bearings. Assemble the body by attaching the nozzle (J-head mount compatible), motor, hobbed pulley on an M8 bolt, bearings, guidler (using Greg Frost's design), and both herringbone gears. Attach long screws with springs; note that the design has been improved for easier attachment/detachment of springs from the top. Be sure to get a hobbed pulley and mount it on an M8 screw between two M8 nuts, as using a typical hobbed bolt is not recommended. Clip the extruder to the carriage and insert one horizontal screw in the bottom part. The fishbone gears and idler are borrowed from another design, with attribution and link provided soon!
