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]

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.

Dual gear is a much better product

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.

Easy to replace. No issues with it after installed.

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.

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

I have a generic CR10 clone that had a plastic extruder and I had issues with the hobbed gear causing under-extrusion. This extruder was a nice upgrade to get rid-off the plastic parts and fix my issue. This extruder provides good tension and makes it way easier to get the filament in, my under-extrusion issues are solved and it looks and feels solid. Overall Im completely satisfy with the investment. The grey color was a plus for me since I was on denial to get a common red one. Bit disappointed that it had a two noticeable dents which kind of ruin the otherwise perfect upgrade. Not sure if it was during shipping but it came in a ziplock bag inside a bubble line amazon paper bag, perhaps a box or more padding would have avoided the dents.

This is awesome for replacing the original plastic one… Works great on my Aquila..

Great item Used on my Anycubic Chiron, other than having to reverse the motor direction and playing with the E steps no major issues I do agree the spring is to strong, I’ll have to replace it with a less strong one soon

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.
