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

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.

Funcionamento perfeito. Recomendo.

Perfect!

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.
