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

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.

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

My Creality CR6-SE got a clog and after changing the nozzle, it was performing very badly with under extrusion (thin filament and spongy, weak, and fragile. prints). I suspected the cheap plastic extruder was worn out, so I bought this relatively inexpensive metal extruder (silver, single drive). It was easy and low risk to install. After installing and putting on a new 0.4mm nozzle, my printer was back to printing very well.Very happy with the purchase, ease of install, and results. I'd highly recommend this upgrade if you have an older or plastic extruder. I can confirm this works perfectly with the CR6-SE.

The media could not be loaded. Instructions are very complicated and hard to follow. However, I had it together and attached to the servo in 10 minutes. Works great and I can now 3D print again! I think the quality is even better now with this metal part instead if the old plastic one. Installed on an Ender 3.

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.

Easy to install, much easier to feed the filament into. Great upgrade and worth every cent. If you have a pressed on stepper motor, you may as well replace that too. The extruder gear is not compatible with pressed on motor style. I'm ordering a new motor with the flat side post and set screws for the gear.

Bought this as my original had broke.Good quality.

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
