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

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

No problems, easy install

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.

if youre having extruder issues try this before replacing the head i had prroblems with my cr10 smart and this fixed most of those problems deff worth a try printing way cleaner now. the stock setup isnt going to cut it you can tighten it but the way they have it setup the spring doesnt always backout when you loosen it i noticed so basically have to take it apart to l get the spring to backoff and its a pain to put together just make life easier and try this before doing anything else oh and get the upgraded bowen tube its blue cant recall the name tho sorry

No issues at all since I installed the kit. It just chugs along happily doing its thing.

It is as it says. install is not hard. does not really effect my print quality any, for good or ill.

no threads on bowden side

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.

The only thing I wish this product has was the wire retainer clip that the OE part has.

This all aluminum extruder is awesome!! Gives you confidence when changing filament that the little handle wont just snap off. Only downside, inlet hole for filament may be unfinished, causing the filament to chafe. I did a quick print filament guide so it now enters horizontal with no issues. This is a good upgrade that will last for a while if only printing PLA+.
