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

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.

純正のはプラなので経年劣化で割れます これはアルミなので早めに変えとけば良かった

Muito bom

Simple, efectivo y duradero. Un extrusor clásico en aluminio sinterizado, con una rueda a 96 pasos en Marlin para microstep de 16. El precio es inmejorable. Buena construcción y se monta sin complicaciones. A veces lo más sencillo es lo que mejor funciona, y yo soy amante de las cosas sencillas y efectivas. Si además es agradable a la vista pues mejor. Este extrusor tiene todo eso a un precio de risa. Es lo mejor que hay para sustituir a un extrusor de plástico. A mí me dan mejor resultado este tipo de extrusores que los dual gear, que sobre papel tienen un agarre mejor, pero que en la practica resbalan mucho más que una rueda clásica por que tienen dientes cortitos. Lo ideal sería un extrusor de este tipo pero con reductora. Aún así un 10 para este extrusor clásico por precio/prestaciones. Totalmente recomendado.

I got this for my Aquila as the feed arm can crack so I thought I would change to this alloy on just in case. The screw used for the spring retention is a little long but it wont be an issue. I cut mine down slight but works perfectly fine without cutting it down.
