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

These are a awesome addition to you fdm printer. These wheels will wear and stop pulling the filament to the extruder. Have these on hand as backups. You’ll thank me later

Good quality, used on Ender 3x

Perfect replacement for the original one

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

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.

The relatively quick and painless replacement of my Flashforge Adventurer 3s original filament feed gear with this one resulted in a significant reduction the annoying filament slip-related knocking noises that most owners of my printer commonly complain about, and slightly improved print quality. I recommend this upgrade to anyone with a Flashforge A3 and Monoprice Voxel 3D printer. There are a couple easy to follow outube videos that walk you the process.
