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

The original that came with the printer is too cheap and bad. My printer stopped extruding everytime because of them. With these my problem went away. I replace them in an Ender 3 v2

Purchased BIQU Extruder Pulley 36Teeth Bore 5mm Stainless Steel Drive Gear for 1.75mm & 3mm 3D Printer Filament (Pack of 5pcs) for 3D printer upgrade. Gears are made of high-quality stainless steel and are a direct fit replacement for Flashforge Adventurer Series 3D printers. Highly recommended!

Replaced the stock pulley on my Ender 3 with this one; the teeth are definitely more aggressive than the one that comes from the factory. That said, quality hasnt changed any (I ordered these after a failure that made my last pulleys teeth fill with PLA) but they are well made and work every bit as well as the stock piece. Ive heard from others that they improved extrusion issues they were experiencing, although i cant say that as I was not having issues before. Would purchase again.

Great replacement gears

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 choice. Same size as the original on my extruder so I didnt have to mess with resetting the e-steps. Well built and like the 2 set screws to keep things locked up.

Product arrived fast and fit well on my x one 2 and solved my under extrusion issue as well as the constant clicking from the old gear slipping.

Much better than stock... This was a nice upgrade to my stock Monoprice i3 clone.

Works very well, definitely an upgrade from the brass. And fits my JG Maker Magic printer.

Good nuff
