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

quick fix to my extrusion problems!

Works very well, definitely an upgrade from the brass. And fits my JG Maker Magic printer.

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.

Using this drive gear to grip a brass rod. Nice. Set screws hold tight on extruder shaft. Used a standard allan wrench. Its loose in hex socket, too much force will round the hex.

These are exactly what I needed and they work great

Perfect fit!

On my Creality Ender 3 the brass stock gear rounded over and Im only printing in PLA. This solved my issue. I had to turn up my flow in Cura to 103% to get good extrusion.

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

replaced the brass gears that keep wearing down..these should come stock with the printers

They work great the higher teeth count eliminates grinding.
