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

perfect last Way longer than the brass ones buy one pack and they will last a long time

Greatest

Brass drive gear had worn out and was slipping. Filament would not feed. The steel gear made my extruder work again. I hope steel last longer than brass.

Perfect fit!

Used on my Ender 3 v2 with great success once esteps were calibrated

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

Definetley doesn’t grind my gears the least bit. Works as they should.

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.

It seems like the stock brass gears are wearing down very quickly. These SS gears have eliminated a lot of extruder skipping. It might just be me, but I did not have to make any other adjustments to the machine other than installing the gears. One should probably recallibrate your esteps. I will probably get to it sometime soon, but at the time I was printing PPE 24/7 with 5 machines and they kept printing good quality so...

Bought these for my 3d printer and they work better than the stock ones! Holds the tubing well and tight! Happy with them.
