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

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

I would rather a brim around the edges so the belts don’t come off.

I purchased these for spare parts for my printer. I havent used them yet but they look identical to the factory parts.

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

Good quality, used on Ender 3x

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.

Perfect replacement for the original one

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.

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!

Great quality, no burrs. Work perfectly, nice an truely round.
