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

This is a must upgrade.

Super easy install. Cant believe what a change it made in my prints.

I was fighting my printer for weeks to get a clean print. My problem was too thin of a print or not sticking/no filament coming out. I replaced all the parts with this kit then boom, instant fix to my problems. I was close to throwing my printer out till I got this kit.

This is an all metal extruder that is far more practical than the plastic extruder on many of the machines. It is well worth switching to this since the plastic ones do not hold up very well and can get worn down from filement passing through them. There is nothing more difficult to deal with than extruder problems well into a long print job. Easy to install(lots of you tube videos to show you how)

These springs are a huge upgrade to the base printer. Combined with the Fokoos glass bed (yes, it fits the ender printer too), it creates a very stable printing platform.

Installed this on my Creality Ender 3 v2 3D printer. Specifically the Bowden tube, aluminum extruder feed and the springs. Now, for these springs on an Ender 3 v2, you may need to cut off a good portion off of it otherwise youll run the risk of not having your bed level.

A nice sturdy replacement for the extruder that came with my Ender 3. Instructions could have been better, but it was a 1 for 1 replacement of the original. Easy enough to do if you pay attention as you are taking apart the original. Came with all the screws needed in case you lose/strip one from the original extruder. Sturdy and everything it is supposed to be. My only problem: The tube coupler that came with this replacement 1) wasnt the same size as the original and 2) the coupler threads didnt match the extruder head itself. This ended up being more of an annoyance than anything else, but it did mean that the part couldnt work with just the parts in the box. Replacement tubing often comes with couplers, and this one uses the same type as used going into the hot end, so I just used the hot-end coupler from my Capricorn tubing upgrade to replace the one with bad threading. Be aware that you might need to/want to buy couplers to make this extruder head work, but they are cheap as long as you are aware you might need them. Chances are your printer kit comes with extras you can use to swap in anyways, so it isnt a big deal.

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

Everything worked great. However, even though I printed well below the 275 limit (235) and the Bowden still melted.

Doesn’t work with ender 5 plus. The handle on the extruder is too thick and the screw won’t fasten it down.
