Upgraded Ender 3 v2 Ender 3 CR-10 All Metal Extruder Aluminum MK8 Bowden Extruder 40 Teeth Drive Gear for Creality Ender 3 Pro/Ender 5/ CR-10 Series 3D Printer

Fixed my feeding issues on Ender 3 v2, I could tell I had issues when prints failed and had "dust" up around this extruder. Thought it was a clogged nozzle but kept happening after checking/cleaning nozzle. Finally replaced old one with this and next print was perfect!

I think all Ender 3's should come factory with this extruder. Its well made. Works well.

Bought this as my original had broke.Good quality.

Easy upgrade dramatically improved my print results. Was using an abrasive filament (PETG-CF) and wore out the original extruder gear. Happy with this all metal design

After weeks of tracking down my Ender 3 Pro issues to the extruder assembly, I figured I'd replace the whole thing since I wasn't sure what was wrong with it. The new all metal assembly went in fine and it mostly solved my issue, but the new spring had just a little bit too much tension and I was experiencing some skipping. I replaced the new spring with the old, original spring and that seems to have done the trick. Most people probably won't have to do this, but if you experience the same issue just use your old spring and hopefully that will fix it for you.

I was looking for some knob handles for my poi, and unsure of the size, shape and weight, and realized it would $15 to buy most pairs I was looking at. They were all 3d printed TPU and I normally just do things myself but Ive got a fairly stock Ender 3 (other than the bullseye cooler) and been told it couldn't do TPU because of the Bowden. Well instead of spending $30 on a couple pairs of handles I decided I'd spend the same on this and a roll of TPU and figure it out anyway. Status quo be damned! I got the TPU first and tried to print it, but got nowhere. There was a gap between the extruder gear and the intake of the Bowden tube and the filament would just push out there and never actually be forced into the hot end. I couldn't even print a purge line.I got this today and installed it. Its pretty simple and similar the original so taking that one out should tell you how to put this in. I just printed my first TPU item and it came out flawless (although at 20mm/s but I decided to start conservative)Now that that works I plan on printing so many other things like endcaps for staffs, and grommets/seals and the like. I'd like to build a beetleweight combat robot and a lot of the armour is TPU. I feel like this opened up a whole new avenue for printing nonrigid items, and has expanded the life of my Ender for much longer as that was a reason i had though about updating. 6 years strong and its been a beast!

Like a lot of others, my Voxelab Aquila's stock plastic extruder arm cracked not long after I got my printer. I printed a replacement arm, and that actually got me by for about 4 months, but that arm started to wear out and was causing unreliable extrusion too.I didn't really feel like I needed to upgrade to a dual gear, or even a direct drive set up for my PLA and PETG printing, so I started looking into the aluminum stock replacements. I've heard these can have issues of their own; the spring can be too stiff, bad hardware, no instructions, and the pivot spacer can be too short which keeps the arm from moving.I'm happy to report, this kit has none of those problems. The stock spring is working fine, parts are all well made and fit great, no problems with the hardware and fittings. Instructions consist of an exploded view drawing with the parts labeled, which was enough for me. If you really run into trouble, there are a bunch of videos out there, or just look at your stock extruder, it goes together the same way. I'd suggest assembling the roller to the arm first, then putting everything else together with the spring being last.So all in all, this is a great kit. I'm surprised a kit of machined and anodized parts like this can be sold for such a low price to be honest. I feel like maybe aside from the brass extruder gear, the rest of these parts should last the life of the printer.If you are shopping for one of these, and seeing about 30 different versions that look the same, just get this one and be done with it.

Feels built well, was easy to assemble and fits correctly on my ender. the weight makes it feel sturdy and can handle fast printing speed
