Creality Original Metal Extruder Drive Feeder Upgrade for Ender 3 Pro / V2 / 5/5 Plus/Pro, CR-10 Series, CR-10S, CR 20/20 Pro 3D Printer Accessories Parts CR10 CR7 CR10S MK8 Kit

This product was delivered timely and was easy to install. Exactly what I was expecting.

Upgrading to a metal extruder is a must on these printers. Mine had a slight burr on the feed hole right before PTFE tube which caused the filament to get shredded as the extruder would retract and feed during printing. Didn’t affect print quality but it made a mess. If you see plastic shavings all over your printer after installing this make sure the filament path is perfectly smooth. A little sand paper fixed the problem for me.

quick release claw breaks easily

Great upgrade to the plastic version, it just makes everything better.

Unlike the original part, your unable to unscrew filliment tube easily when a jam occurs. Filliment is now stuck. Will be going back to original part and returning.

I bought this because my Ender 3 V2 plastic extruder cracked under the bearing. (Dont they all?) After the kit arrived I examined it to make sure all the parts were there. They were. There has been a positive change in the design to use a normal bowden tube fitting just like the original plastic extruder. The product picture is no longer current. Unfortunately during assembly I found that the bushing that the tension arm rotates on was too short. This resulted in the arm not moving when the bolt was tightened. I fixed this in two ways. First I sanded off the anodizing from the bottom of the arm gaining a little more clearance. Not enough. Second I put the little bushing in a drill and used a small file to lengthen the small diameter tube towards its top. After a couple tries it was long enough to tighten down but not keep the tension arm from moving. Now the extruder works great even with harder filaments like wood and PETG. I suspect the part is correct when machined but after the red anodizing there is not enough clearance. Pretty easy fix but shouldnt have had to do it.

I ordered this to replace a broken plastic one on my Ender 3 v2, major improvement. Required a little work to get the spring in place (very tight fit), but it works great.

Better than the plastic ones that come on it. Put them on all three of my printers now.

Product was up-grade to similar model on youtube install videos. Upgraded coupling connection.

Arrived quickly. Was exactly as described and pictured. Have had no issues at all. Feels much more solid than the plastic one that came on the machine. Would definitely buy again.
