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

Great upgrade from the stock plastic one that cracked on me. Dont think Ill have any issues with this. Been going strong for 4 months now

Very nice upgrade parts fit well installed easy. Came with all parts needed to put it together.

The springs are wayyyy too long for my ender 3 pro. I tightened them as far as they could go, and the nozzle still scrapes the bed. The extruder is nice but disappointed in the springs.

Metal extruder arrived just as my plastic one broke right at the threads . Great upgrade.

⭐️⭐️⭐️⭐️⭐️

Why doesn’t creality just include this ? Bought this for my 2nd printer setup knowing the stock plastic ones lack in durability. I decided to try the stock one until it wears out and I couldn’t get any filament thru the stock plastic extruder. This one works perfect ! Strong and clean install. Effortless to load filament. I prefer the way this one looks. It’s unfortunate that creality doesn’t include this in their printer kits. The spring screw included didn’t fit for me so I had to use something else. Could be user error

If you got an Ender 3 V2 this kit is a must. Its very affordable, easy to install, and best of all it works! Havent had to level my bed in over 200 hours of printing.

Great metal extruder kit. The springs alone are a biggggg upgrade. Keeps that bed level, and if you need to relevel anything, it is just bare adjustments to get it back where it needs to be. The tubing is great as well, makes it easier to switch out and feed filament. Just follow directions on YouTube, but make sure to take a few pics of your current setup prior to taking things apart. Just in case....

Everything installed like you would think, the filament feeds smoothly and it feels of much more quality over the factory Ender 3 unit.

I like the spring tension adjustment screw feature. However i do wish there was more information on that in the instructions.
