Creality Original Metal Extruder Drive Feeder Upgrade for Ender 3 Pro / V2 / 5/5 Plus/Pro, CR-10 Series, CR-10S, CR 20/20 Pro 3D Printer Accessories Parts CR10 CR7 CR10S MK8 Kit

Product was up-grade to similar model on youtube install videos. Upgraded coupling connection.

For the minimal cost and the likelihood of the plastic feeder eventually breaking, I dont understand why this isnt included with the printer out of the box. My only complaint is that spring/tension assembly doesnt go together quite like the feeder that comes with the printer; and instructions arent included. Im sure a small fold-out isnt included to keep the price down, but I cant imagine a simple exploded diagram would break the bank. Even a picture on the package would have been all I needed. And no, Im not interested in looking online for something that should have been included. Fortunately its easy enough to figure out with a little trial and error.

All parts were there, easy to assemble.

You get all the parts you need and the quality is top notch, but no directions :).. with the spring and screws there is some finickiness to getting it aligned and at the right tightness that you dont have to deal with in the out of the box extruder (on Ender 5 Plus) for me.. but once dialed in its a great upgrade...

I had read so many reviews about the factory extruder on an Ender 3 V2 failing within the first so many prints that I purchased this at the same time I bought my 3D printer. Swapped out the plastic one before I ever powered it on and havent looked back. So far its been smooth printing as Ive almost finished my first spool of filament and the second one will be here in a couple days.

did exactly what i need it to do easy to install

Better than the plastic pieces... mostly. The filament feed holes dont exactly line up. When printing something where the filament needs to retract a lot, it squeaks LOUD!

This replacement/upgrade extruder is made of high-quality parts which is nice considering how often upgrade components are complete junk. It works as expected and does a good job.

Works good last long time.

Just received pieces/parts in plastic bag. No installation instructions whatsoever.
