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

Review.

I bought these to replace the one that came with my Anet A8 extruder and it works great! Way better than the one that came with my printer with less than 24 teeth.

These wheels work and fit perfectly but they wear out quickly. I do a lot printing and have to replace them every few weeks. If you dont print 24-7 this might not be an issue for you. I dont mind having to replace them because of how cheap they are. I like to clean and lubricate my printer regularly so I just replace the wheel when I am doing my preventative maintenance.

Works well

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.

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.

Fit perfect and worked great after e-step calibration on cr-10s.

Works well

A vast improvement over my stock brass gears. If you are having extruder issues, this is well worth a try to fix the problem. Used on a stock Ender 3 extruder, and I had no need to change e-steps (checked before and after, same result). YMMV, but this fixed my under extrusion.

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.
