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

good 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

Easy to install and helps me with my CR10 issue

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!

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

Very durable accurate fit works perfectly.

I got this new extruder for my ender 3 max, old one had worn a groove from filament. So far so good. Easy to install, just remove tension spring for access and turn the gear to access grub screws. Print quality had huge improvements.

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!

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.

correct size and seem to work fine
