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

Perfect fit!

The angle between the two position screws are closer to 45-60 degrees.

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

Old brass extruder gear wore out quickly. Bought these and it has 0 wear to it. Buy if you need new extruder gears.

Worked great.

Perfect fit to replace the worn brass part on my jgaurora A5S.

They work great the higher teeth count eliminates grinding.

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.

Seem solid and work great in my mk8 extruder.
