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.

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.

I had some issues with the filament not feeding properly. This part fixed my issue! It is also great to have some spares!

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.

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

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.

What an improvement. Pics show new one installed next to the old one. Best part is I now have spares in case I ever need to replace this one. Not hard to replace, just check out YouTube videos on replacement.

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.

Very durable accurate fit works perfectly.
