CR-10, Ender 3, Ender 3 Pro Direct Drive Mount Aluminium Dual Gear Extruder. Remix from https://www.thingiverse.com/thing:3369418 I used with Satsana Fan duct https://www.thingiverse.com/thing:4377334 ### Installation Remove your X carriage and the two v-slot rollers, hot end assembly, extruder, and extruder motor. Press and/or epoxy the spacers into your direct drive extruder bracket. Reinstall the v-slot rollers and the direct drive extruder bracket onto the x-axis carriage. The bracket locks into place on the x-axis carriage quite securely. It may take some force to make it snap into place. Install the extruder and extruder motor onto the bracket, but leave the screws loose enough for the motor/extruder to slide freely in the slotted holes. Cut a piece of bowden tube about 35mm long (this measurement may vary depending on your hot end/extruder setup) and insert between the hot end fitting and the extruder. Test the fit of the hot end, and trim the bowden tube a little at a time until everything fits properly. Reinstall and tighten everything that goes on your x-carriage - extruder, hot end, fans, auto leveling sensors, etc... Reinstall the x-axis carriage onto the z gantry and adjust the v-slot eccentric. Install and tighten your belt. It is necessary to extend your extruder motor wires and re-route them through the hot end braided sheath to retain your full print volume. I had some leftover 4-conductor RGB-LED extension cables that I spliced/soldered in. The wires and filament need to be routed in front of the frame uprights, or you will lose Z height as there will be interference with the top cross bar. If you drill out the mounting holes on the stock CR-10 spool holder bracket to 4mm, you can use any M4 screws and t-slot nuts to mount the spool on the top cross bar, Ender 3 style.
