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

Extruder base does not have a threaded output for the fitting to the Bowden tube, I think I was supposed to put a supplied plastic plug into the non threaded hole and thread the fitting into it, that did not work for me. Put all the original parts back on and ordered the correct extruder. The printer is an Ender 3 V2 and it is in the list of compatible printers for this part.

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 The product picture is no longer current.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.

Great upgrade for a 3d printer. If you have an ender 3 just do yourself a favor and upgrade to this piece.

This upgrade to my Ender 3 printer helped with my print issues I had. It made the filament feed correctly into the Bowden tube.

Works good

All parts were there, easy to assemble.

quick release claw breaks easily

You get all the parts you need and the quality is top notch, but no directions :).. with the spring and screws there is some finickiness to getting it aligned and at the right tightness that you dont have to deal with in the out of the box extruder (on Ender 5 Plus) for me.. but once dialed in its a great upgrade...

This does seem to be an official Creality branded kit that Im sure will fit any of the advertised units. It matches up perfectly with my CR-10 v2. Im not convinced about the quick-release claw. First, there doesnt seem to be any replacements available and no extras are included. This will certainly wear out over time, and, functionally, it is still a push-pull insertion thing so I dont really see why it would be any better than the standard couplers. Also, since this isnt threaded, you cant even go back to the old ones. We certainly need some sort of improvement over the current PTFE tube couplers, but Im not sure this is it. A big one for me is the toothed gear. I bought some generic replacements and they only had one grub screw. This one has the proper two. That is almost reason enough to go with this kit over some other. Priced well, official Creality, recommended.

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.
