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.


  • Increase print quality, simplify retractions and fix extrusion.
  • Lightweight and rigid mount lets you to print fast.
  • Print high temp and flexibles – up to 260ºC+ on the stock hot end.
  • Simplify filament changes.
  • No firmware flashing.
  • No cutting / splicing wires.
  • Works with stock extruder and hot end.
  • Fits many printable mods.
  • Simple 20 min. install (instructions provided).

Tech Specs

  • CNC machined 6063 aluminum.
  • Injection molded fittings.
  • Weighs ~478g installed (w/ hot end, extruder, motor, fan shroud, wiring, all fittings, hardware).
  • Wire harness extension included.
  • USA-made PTFE rated for 260ºC+.

Product Features

  • A direct drive extruder improves extrusion and retraction by removing the need for the Bowden (PTFE) tube.
  • Installs in 20-30 minutes with NO firmware changes, no cutting or splicing wires.
  • The PrinterMods MDD is lighter and less expensive than other direct drive systems, while offering the same or better performance.
  • No X,Y, or Z axis build volume lost. Compatible with your stock CR-10 or Ender 3 hot end and extruder, as well as many others.
  • Engineered and manufactured in the USA.

UPEMOO Upgraded 3D Printer Parts MK8 Extruder Aluminum Drive Feed 1.75mm for Creality 3D Ender 3, Ender 5, CR-7, CR-8, CR-10, CR-10S, CR-10, CR-10 S4,and CR-10 S5


This is the MK8 style extruder feeder drive made completely from machined aluminum. this part serves as a replacement for that many 3D printers. the plastic feeder is prone to wear as the filament is pulled into the feeder if the filament is pulled from above or below the intake. it will effectively “saw” at the plastic over time. the filament intake on this model is beveled as well, to prevent scraping the filament as it is pulled into the feeder which is a common problem among some cheaper all metal feeders.

This modified MK8 Extruder has a filament guide tube, all screws, spare drive gear, and upgraded Bowden tube fitting. Our design gives complete support of flexibles from the intake and output ends. We’ve reduced the price and complexity of printing flexibles. It will also allow to print faster with sustained quality and no risk for grinding the filament.

It looks amazing, and performs better than the plastic version included in stock printers. It allows you to print flexibles, and regular plastic filaments.

Also included is an upgraded bowden tube fitting, which does not slip, as the stock one can. Every screw and washer we would recommend for this installation is included.


-This extruder set is great for Creality 3D printer.

-Made of high quality metal material.

-Easy and convenient to install and use.

-With high quality and durable performance.

-100% brand new

Package List:

-Mounting screws

-Aluminum MK8 Extruder frame, with bored intake hole.



-Brass extruder drive gear

Product Features

  • ✔It is Right hand extruder upgrade Kit.This high quality all aluminum construction is guaranteed to last for years!
  • ✔Upgrade from your stock plastic or 3D printed extruder feeder drive as they can wear over time, scrape filament as it is pulled into the printer, or even break when squeezed to release the filament.
  • ✔This extruder feeder drive is compatible with nearly all models 1.75mm filament of 3D printers MK8 bowden extruder frame. No need to change stepper motors or other mounting hardware.
  • ✔Great for use with any Creality 3D printer Ender 3/3Pro,Ender 5,CR-7,CR-8, CR-10, CR-10S, CR-10 S4, CR-10 S5, CR-10 Mini, CR-10 Plus.
  • ✔The advantages of our extruder drive is you have better stronger pressure pushing the filament into the printer nozzle and so will improve on the printers’ performance. Our extruder kits have an adjustable bolt so that you can adjust the pressure of the extruder gear as needed.
