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 kind of tightly. It may take a little 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 loose 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.
