thingiverse

Just like my previous nema14, this is nema17 version, can be used on nema with longer than 25mm shaft. It use the motor shaft as extruder shaft to. And since its rotate at different speed, please give it a high quality grease to prevent wear on both shaft and MK8 gear. Please check print setting notes. Bearing use 625 For clipping the idler to the body, use metal PEG like on the photo, or you can use other clip. Print Settings Rafts: No Supports: Yes Resolution: 0.15 Infill: 50% Notes: Support is for the Body2 only. For body1. rotate X 180 For idler, rotate 90 For gear, i use xy compensation -0.12 on my printer using Slic3r Print gear 3x Post-Printing Make hole good Manually drill with 3mm bits for the Gear1 Manually drill 5mm bits for Orbit, do not drill the 3mm hole on orbit. Carefully put the MK8 into orbit and glue it. make sure it straight so perhaps, it will be better if you can use motor shaft to help then glue it a little using super glue. Take it out and put more glue. Clean the shaft and put the motorgear down to bottom of the shaft, and put super glue. Be carefull. Lubricate all gear using good grease Use small M3 to lock in place 3 gear to orbit. Print m4rr to help put M4 nuts to PTFE tube 4mm. or just use easyfit with 5mm thread.
