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

Seem solid and work great in my mk8 extruder.

These seem like they will hold up better than the brass. They have two set screws and were an exact replacement for what I had.

Perfect fit!

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.

Review.

Great replacement gears

Not sure what I was using before, but these saved my printer to now print TPU like gang busters! If you are struggling with printing TPU, these are grippy and work. It may not be your only problem, but it will eliminate a variable for why it may not be working..... (TPU is hard to print). Worth the price and should last a lifetime.

These are exactly what I needed and they work great

Work as designed to replace the OEM item that was replaced.

Actually Im testing in my CR-10, in this short time I dont have any problem
