Creality Upgraded MK-8 Metal Feeder Extruder Frame Aluminum Gray Bowden Extruder Drive for Creality Ender 3/3 Pro/3V2/5/5 Plus, CR-10 Series, CR -10S/20/20 Pro 3D Printer

The original arm failed only a month or so in. This new aluminum assembly fits right in its place, I didnt even bother to pull the old gear off the motor. Everything has been working great since, Ive printed PLA, PETG, TPU, and even hot-swapped a few rolls, nothing has phased this extruder.

You can buy a duel gear setup for similar cost, but this does what its intended to do. If youre new and replacing a part, go with this.

This is a must for all ender 3 models

I used the original spring from my printers extruder as the one in this kit is too stiff. Also, its a bit wonky how the spring is retained on two screw heads.

Great upgrade. So cheap it should be on Ender 3 series from the factory. Totally eliminates the inevitable failure of the factory plastic extruder.

This fit and worked amazingly. Had no issues with it functioning and working as it was supposed to.

Definitely see the difference in my prints over the stock plastic extruder.

I bought this as a promotional add on when I purchased my Ender 5+, not really knowing much about the printer or parts upgrades. Im glad I did- during the swap assembly I discovered the factory extrusion clip had a hairline crack where they inserted the brass thread nut. They should make the aluminum standard, at least on the Plus models. The downside is theres not much in the way of instructions, you have to check the old part and figure out the best order for disassembly and reverse engineer it using the parts diagram.

Exactly the extruder upgrade your looking for. Very reliable

Good product and installed easily. Liked the combination of components.
