Redrex Ender 3 Extruder MK8 Metal Bowden Drive Feeder Upgraded 3D Printer Parts Compatible with Creality Ender 3 V2/Ender 3 Pro/CR-10 Series and Other Reprap Prusa 3D Printers[Right Hand]

While it seems to be a high quality unit, the brass gear part that move the filament bites into TPU and jams regardless of pressure. I tried two different brands of TPU (Sain Smart and Overture) and jammed on both. I backed off the spring to the minimum pressure and it still doesnt work. After inspection and comparison with the factory provided gear, I noticed that your gear teeth are very sharp and way deeper than the original part. I CHANGED BACK TO THE ORIGINAL GEAR AND SPRING AND THEN PRINTED TPU JUST FINE.

Out of all the upgrades I have done on my ender3 v2, this one has been the most noticable as far as print quality. For the price, its been one of the cheapest upgrades (other than the ones I printed my self). Now if I can only find a bed that gets good consistant adhearence print after print. Also, switching this over to Direct extrusion will be easy and will be even better.

Dual gear is a much better product

An upgrade that Im so happy I did. The all metal extruder is adjustable where the OG Ender 3 isnt and it lets you fine tune the filament extrude. the build quality is greatly done no sharp edges and really finished. the installation was easy took like 5 mins of removable of old and installing the new. If your looking to upgrade your extruder this is the kit you should use.

This was a great upgrade to my stock plastic extruder. It is easy to install and was a breeze setting up. Make sure to calibrate your extruder after installing since it will be slightly different. The tension on this is perfect and I don’t hear slipping or clicking when printing now. I bought this for my Ender 3 Pro with stock extruder motor.

Came to CY/EU very fast! external packaging was a bit big but hey. Everything in the box and wasnt expecting a cog wheel- maybe i didnt see it in the description. worth buying from seller- will look at what else they have too

Ive had this extruder for a few days now and no matter what I do I cant get it to consistently push filament out my hot end making it unusable. The extruder can easily push filament through my bowden tubing but begins slipping when trying to extrude. I just bought a new hotend with bowden tubing a few days after I ordered this so I know its not my hotend thats clogged.

Awesome replacement for my stock extruder that broke. Great value.

Easy to install. Solid quality. Grips filament firmly. Good value for the money. Prompt delivery

Works like a champ and is a solid replacement for my ender 3 v2s garbage plastic extruder that cracked on me. Runs nice and smooth.
