Creality Upgrade Ender 3 Extruder, Ender 3 V2 Upgrades Metal Extruder Aluminum MK8 Bowden Extruder 40 Teeth Drive Gear for Ender 3 Pro/Ender 5 Pro/Ender 5 Plus/CR-10 Series 3D Printer

I was having a problem with under extrusion on my ender3 v2 and picked this up and it fixed the problem. This should be on all of their printers.

The stock, all plastic extruder on my Ender 3 broke the first week I had it. This one wont break. The tubing is very good and they include enough for 2 tubes. I havent used anything else in the kit yet.

Like many others my CR6-SE extruder didnt last long. I got this as an upgrade and its a direct fit replacement. I will say the instructions leave a lot to be desired and at first I messed up the spring tensioner with another part. However I noticed quickly and swapped them around. It works great and is a huge improvement to the stock extruder.

Replaces many plastic parts, and these springs have made leveling the bed alot finer. Each and every print the bed would get drastically out of level; at time screwing up the print. Since I put these I have alot less bed leveling issues.

My brothers ender 3 now look great and extrudes better. The springs are also really nice. makes it much harder to accidentally mess up the leveled bed. Though I would suggest every one with an ender 3 (who doesnt utilize a bl touch or the like) uses a mesh bed level setup.

Dimensionally identical to the plastic setup that comes stock on the Ender 3 and Ender 3 Pro. It’s a direct bolt on swap. You don’t even have to worry about the pressed on brass gear on the stepper. Just leave it alone and it works with this one just fine.

No bed leveling springs! Thats what I wanted the most.

Despite being sold as more durable it still gets eaten up by some filaments, glow in the dark for example. It would be nice if they used high grade aluminum instead of cheap pot metal. Ideally someone should come out with a stainless steel one, or at least a stainless steel lever so the filament doesnt cut grooves in the eye.

Factory upgrades are always the best bang for the buck. Nice fit & finish on the extruder, springs work well too. Bowden tube is the best part, make sure to do the heat-break washer upgrade as seen on the internet.

definitely a needed upgrade for my ender 3v2
