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

very easy to install on an ender 3v2 and I didnt even have to adjust my e-steps

Bought these for a Dremel 3D45. As I type this Im sin the second hour of a 28 hour print and everything seems to be running very smoothly. Im hoping that these will stop the frequent jamming issues Ive been having. Ill update after some more serious print time.

good good in the hood

Work as designed to replace the OEM item that was replaced.

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.

Worked good on my cr-10s

A little bigger than stated 5mm inside diameter.

Fixed my Maker select V2 with these, dont know if these match the factory gear as I dont think mine had a factory gear in it when it failed. But it matched whatever mine had. Only critique is that the gears seemed like they got banged around in transit so there were some light existing marked/gouges on them. I suspect its not an issue, I just used the one with the least and it worked great.

Filament is the natural prey of a 3d printer, and a printer with a brass feed gear will inevitably starve to death as the teeth wear down, I refit mine with these stainless steel gears, which contain many more teeth and grip better than the standard brass ones. Now the filament in my boxes tremble in fear at the newly terrifying maw of my printers.

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.
