BIQU Extruder Pulley 36Teeth Bore 5mm Stainless Steel Drive Gear for 1.75mm & 3mm 3D Printer Filament (Pack of 5pcs)

I got some of these to go with a metal extruder for my Ender 3. Theyre probably strong enough to drag a refrigerator down a hallway. Get some. Throw your brass in the trash.

Perfect replacement for sender 3v2. Old brass piece was worn out from clogs but this get it back up and going in no time. Will need to adjust esteps.

Great replacement gears

Working well so far. Ran a kilo of carbon fiber through so far without issue. Do wish they had two grub screws instead of just one.

Greatest

I used this gear to replace my stock brass gear on my Anet A8. I somehow managed to strip the teeth on the original gear. Figured I might as well go overkill on the replacement. This stainless steel gear does great on my extruder. It grips the filament and doesnt let go until I press the release lever. I would highly recommend this as a first upgrade to a direct drive extruder.

Actually Im testing in my CR-10, in this short time I dont have any problem

Worked great.

replaced the brass gears that keep wearing down..these should come stock with the printers

Works well
