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

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.

Works very good in my CR-10

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

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

Works great!

correct size and seem to work fine

Great product.

Works as intended
