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

If you have a plastic extruder, my advice is buy this immediately. Plastic cracks and affect retraction and feed. Go metal!. My gear was wearing, had an incident, nozzle died and extruder just spun on the gear for who knows how long. Got this the next day and bak in business.

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.

Does not sit correctly on the extruder-motor plate, thus, filament does not line up correctly when coming up through bottom of extruder, to the little hole that leads to the Bowden tube. No way to see in to guide it correctly. No instructions came with it Not sure which it DOES fit, but definitely not Ender 5 plus

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.

Works good

Easy to install, did not affect print quality. No affect on print accuracy. But looks nice. However l was unable to use the extruder knob, due to the shaft being to short, see picture. Also filament now slips with a distinctive click. I do not recommend.

Quick install, parts have the same specification as original but in metal. Definitely an upgrade.

Did not come with instructions

Unlike the original part, your unable to unscrew filliment tube easily when a jam occurs. Filliment is now stuck. Will be going back to original part and returning.

HUGE improvement to my 3d prints. Why every 3d printer doesnt come with one of these is beyond me. If you have a plastic extruder, get this. Well worth the price and effort to change. Made a drastic difference in my prints. Highly recommend!
