Creality 3D Printer Parts 5PCS Brass Extruder Wheel 40 Teeth Drive Gear for CR-10.CR-10S,S4,S5,Ender 3,Ender 3 Pro,Ender 3 V2

Works as expected. The teeth on the one that came with the printer finally wore out after continously printing for months on end. Still on the first one in the pack after about a month of it being on the printer. So far so good.

Good quality, used on Ender 3x

Great direct replacement. Took seconds to swap out. Those things wear out after a few hundred prints and affect print quality.

Without these i would have given up on 3d printing. After switching between many extruders and gears these are by far the best for making sure there is no gear slippage. Make sure though you have the right extruder or it wont fit.

I replaced my pressed-on gear after it stripped out. This got my rig working again but after a few weeks I see that the brass teeth are wearing down already. I think it won’t be long before I’m replacing it again. I think stainless gears would be better

Used on CR-10 S5, OEM fit, working great.

Soes exactly what it is supposed to do and is a direct replacement for the Ender 3 printer.

Really good drive gear for most printers out there. I like that it has two adjustable screws to keep it in place. It lets me adjust the gear slightly to an unworn spot on the gear as it wears naturally over time.

These are perfect swap parts for the Ender 3 motor to keep your filament going. My old one had over 700 hours on it and started to slip a little, put one of these on and no problems since.

These are an exact replacement for the Ender-3. Same quality as the original. Definitely needed if you print a lot. Nice that I have extra on hand. Will buy again when needed!
