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

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.

Im only getting about 12 hours of print time before the teeth are too warn to work. I have only used PLA. The stock brass drive gear lasted MUCH longer

Perfect upgrade for extruder gears, used in both direct drive and Bowden configurations and works perfectly and cheaper than most, definitely a win.

No problems encountered with these gears - solved my extrusion issue.

Description says 5 extruder gears when I received 4. Probably wont even use 4 but its not the point. Would like to receive what I actually paid for.

Worked great.

I bought these last year and replaced all my printers with these. And they are far better then one comes stock. The stock wore out so quick. Once I put these on i haven had any problems with filament not getting pulled or filament slipping. there are currently being used for my CR-10s and Hatchbox alpha and not one issue. These are really high quality and at this price point its hard not to get them. I highly recommend getting these and having some lying around in case anything happens. Its better to have spares then to be down while new ones get shipped. Again these are much better then stock. Highly recommend!

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.

Seem solid and work great in my mk8 extruder.

Perfect fit!
