Ender 3 Direct Drive Extruder Conversion Kit, Fits Creality Ender-3, Pro & CR-10 3D Printers, Complete Kit Requires No Firmware or Wiring Modification

The MDD v1.0 is the easiest direct drive conversion available for your Creality Ender-3 or CR-10 3D printer. Fully installed with the MK8 hot end and MK10 extruder, it’s lighter than a Titan Aero and takes just 20-30 minutes to install– with no firmware changes, no volume loss, and no cutting or splicing required.

While compatible with many hot end and extruders, the MDD was engineered to turn your stock components into a powerful direct drive system with no additional hardware needed, making it the simplest direct drive system for your Creality 3D printer.

No firmware changes are needed when using stock extruder and hot end, though we recommend starting with a new slicer profile with a retraction of 1.0mm and ooze control (coast, wipe, etc.) turned OFF.

  1. Does it’s Job I was able to convert my original bowden CR-10 to a direct drive using this kit. The process took about 15 minutes and required no additional parts. The aluminum replacement support plate is solid and well built as well, and instructions were simple and clear to follow.There are a couple of things to be aware of when installing this kit:1.) Heavy! because the stepper motor is in front of the extruder. The entire print head is top heavy, it puts a lot of weight on the X…

  2. Excellent materials, great Direct Drive Kit. Excellent Direct Drive kit. Fits perfectly on my Ender 3 Pro. The Hero Me didn’t fit, but the remix from Teaching Tech fits like a glove. I’m using 1mm retract and no coast and almost got zero stringing using PETG. The quality of the materials is awesome, no 3d printed parts, all metal main plate. Easy instructions. The suggested wiring is a little weird so I routed the cables as the original. Looks clean and neat. The quality of my prints improved a lot.I 100% recommend this kit…

  3. Almost perfect! Recommended buy, with a caveat Damn near perfect basaraba style direct drive modification. All of the parts fit perfectly.The solid metal back plate just fits right and with no play once the bottom roller is adjusted on it. Screws were perfectly sized and fitted for the entire assembly. Instructions were extremely helpful, even for a person who had never installed one of these mods before I was able to go from start to finish with in only a few hours without a video tutorial. Also their thank you card was an awesome touch…
