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

Perfect replacement for the original one

I was having a problem with my Flashforge Adventurer 3C printer with the filament not feeding properly. These gears are a good replacement for the stock feed gear. My problem ended up being something different, I had to calibrate the platform with a piece of receipt paper to completely resolve the problem, but these gears do work perfectly so if you have this printer, don’t be afraid to order them. I did notice they come with two set screws, I only used the one set screw that goes on the flat part of the stepper motor and simply removed the second. Took about 10 minutes to change this part. Hope this helps!

Used on CR-10 S5, OEM fit, working great.

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

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

I would rather a brim around the edges so the belts don’t come off.

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

Great product.

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

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.
