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

Well, Amazon reminded me to review this today, which was appropriate seeing as I ordered this over 2 weeks ago. Literally today, the coupler that connects the PTFE tube to the printer stopped biting on the tube, and pushed it right out. Filament was everywhere. Solid product other than that, but have extra couplers on hand.

Alright so the product works great but Theres a very important detail missing. The ender 3 pro has its extruder gear press fitted to the stepper motor. If you want to replace it with the one in this kit you will need to heat it with a torch till its glowing red before you can take it off. Alternatively you could also buy a new stepper motor

It did its job

This is a must-have upgrade over the plastic version Creality includes on most of their printers. For the arguably low price point, I dont know why they wouldnt just include this on every printer they ship out and do away with the plastic version altogether. Ive purchased a few of these for non-Creality printers as well and it works just as good either way. Watch out though, there are cheap variations of these floating around out there made from soft aluminum and inconsistent tolerances. They are almost guaranteed to strip out or tear your filaments up. Ive tried to save a few bucks in my day and paid the price for it after having to come back and buy the legit Creality brand.

Dont go by the printed logo as to which end is up. Other than that its an easy install with an upside down logo. I also couldnt get the spring screew in place but have had 0 issues with it not installed

This is not the extruder you are looking for, just get a dual gear one this one isnt made correctly.

Came with many good parts for upgrading my 3d printer, wish the instructions were better for each part but all in all it’s pretty easy to install

Definitely worth the buy.

I bought this to replace the feeder that came on a super cheap 3D printer. It seems a little more difficult to assemble than one I have from a different supplier on my other printer. Once assembled, though, It is a well designed feeder and I recommend it to anyone wanting to update. The main advantage is that you can manually retract filament, as when you change colors, without spinning the stepper motor, which I have been told is to be avoided.

Nice upgrade to my Ender. Springs have greatly improved prints. Dont need to recalibrate Plate as often. Tube looks good but Im not sure how it well it helps. But my prints have been good.
