Based on https://www.thingiverse.com/thing:3369418 Made forXCR3D Titan extruder version (which is cheap "optimized" clone version) Very light and simple design to make it perfectly align with hotend To be used with Pancake motors up to max 25mm (some people report that is still too thick so be warned that you need everything perfectly aligned, for me it worked with 27mm) I'm using it now with22mm, since this is geared extruder they have more than enough torque and they are lighter so that is recommended Best to print with PETG or ABS with 4+ shells but ~20% infill to keep it lighter https://youtu.be/AmEaNAwFSfI?t=496 Using lower layers like 0.12 - 0.16 should be better https://youtu.be/fbSQvJJjw2Q?t=666 PLA is fine but make sure to run as low vrefs as you can to keep the motor as cool as you can (without skipping steps obviously), otherwise PLA will deform with time You can also try annealing PLA but that will change dimensions Holes for mounting on the wheels will be very tight so best to insert it by heating like with solder iron for inserts https://www.lulzbot.com/learn/tutorials/heat-set-inserts-tips-and-tricks This requires longerPTFE tube (around 80mm in my case) and the best is to unscrew whole hotend fan mount and hotend itself so you can easily mount all of this then you can insert hotend from below after you finished mounting your extruder above and find correct PTFE length by aligning hotend holes with original position as expected Print Settings Printer Brand: Creality Printer: Ender 3 Rafts: No Supports: No Resolution: 0.12 - 0.16 https://youtu.be/fbSQvJJjw2Q?t=666 Infill: 15 Filament: Jupiter 123-3d.nl PLA Silver Category: 3D Printer Extruders
