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

Easy to install and helps me with my CR10 issue

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 as intended

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