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

Got these for the ender 3 extruder they work much better than the brass ones that came on it.

Installed on a Creality CR-10s. Worked like a charm and have a few extra.

Using this drive gear to grip a brass rod. Nice. Set screws hold tight on extruder shaft. Used a standard allan wrench. Its loose in hex socket, too much force will round the hex.

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.

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.

good good in the hood

The original extruder pulley that came with my 3D printer wore out very quickly. Replaced with this & works great. No more filament slipping.

Works perfectly. I did not have to do anything to the estep
