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

I replaced my pressed-on gear after it stripped out. This got my rig working again but after a few weeks I see that the brass teeth are wearing down already. I think it won’t be long before I’m replacing it again. I think stainless gears would be better

My step motors cog was worn down and press fit. Ordered a new 40-42 and this set. Completely fixed my issue

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

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!

worked perfectly on my 3d printer, the CR-10 mini. Thanks

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.

Very durable accurate fit works perfectly.

Great product.

Perfect replacement for the original one

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