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

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

Soes exactly what it is supposed to do and is a direct replacement for the Ender 3 printer.

Good quality

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.

Works very good in my CR-10

good product

What an improvement. Pics show new one installed next to the old one. Best part is I now have spares in case I ever need to replace this one. Not hard to replace, just check out YouTube videos on replacement.

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

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.

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!
