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

Does not sit correctly on the extruder-motor plate, thus, filament does not line up correctly when coming up through bottom of extruder, to the little hole that leads to the Bowden tube. No way to see in to guide it correctly. No instructions came with it Not sure which it DOES fit, but definitely not Ender 5 plus

I picked this up as my first upgrade to an Ender 3 v2. The Creality metal extruder drive was fairly easy to assemble reversing the steps that I used to remove the original plastic extruder and with the help of a similar youtube video as there are no instructions included in the package; a little surprising. The process of assemble still took less than ten minutes. After re leveling the bed it was time to test this all metal extruder out. Immediately, I was somewhat impressed with what it created using PLA, but for those of us that struggle with TPU filaments, this upgrade is a must! What a difference in printing ability when it comes to TPU. I think the all internal parts, with no need for the added coupler, helps in creating a direct route to the tubing with no gaps. Very impressed with the quality of the parts and the enhanced printing abilities that are now attainable. I would definitely recommend this to anyone that still has the original plastic extruder. Eventually the plastic does degrade and will affect print quality, where the metal extruder will hold up for a much longer period of time while providing consistent great results.

It came in pieces it wasnt already assembled like in the picture!

HUGE improvement to my 3d prints. Why every 3d printer doesnt come with one of these is beyond me. If you have a plastic extruder, get this. Well worth the price and effort to change. Made a drastic difference in my prints. Highly recommend!

I ordered the kit. Came as pictured, no way to attach Bowden tube holder. Ordered replacement. SAME THING

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.

The best thing to happen to 3d printer since the printer, extruding is everything physically, but the plastic factory crap is worthless, if amateur or professional you need this 99% METAL ! BUT nozzle replacement gadget(weird)-its great, all my previous issues was the extruder cold end tool. Add this for a mere 14 bucks no more issues

This has an updated bowden tube output. No threads for a normal pneumatic coupler. Seems to work great so far.

5 stars so far. No issues, just had to recalibrate e-steps and I was good.
