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

Worked great.

Review.

Was starting to have trouble with the extruder skipping. Replaced the stock brass gear with one of these and problem solved. Cant really speak to the durability as Ive just started a print with the new one, but the improvement in extrusion was immediate. For the money you really cant go wrong if youre not quite ready to upgrade the extruder.

quick fix to my extrusion problems!

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

Better than enders part

I like these a lot better than the brass ones that the Ender 3 comes with. They seem a lot more durable and grip pretty well. I dont think Ill have to replace one of these for a long time.

Installed on a Creality CR-10s. Worked like a charm and have a few extra.

Greatest

Seem solid and work great in my mk8 extruder.
