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

The original extruder pulley that came with my 3D printer wore out very quickly. Replaced with this & works great. No more filament slipping.

Fixed my Maker select V2 with these, dont know if these match the factory gear as I dont think mine had a factory gear in it when it failed. But it matched whatever mine had. Only critique is that the gears seemed like they got banged around in transit so there were some light existing marked/gouges on them. I suspect its not an issue, I just used the one with the least and it worked great.

Switched my worn Ender-3 brass extruder gear with this one. Size was so close that I didnt bother with E-step calibration. Working great.

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.

Slightly smaller than standard for my CR-10. Needed to play around with the feed rates to get the right flow. Dramatically less feed slippage though, and Im assuming the steel will be more durable than the stock brass parts.

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.

Working well so far. Ran a kilo of carbon fiber through so far without issue. Do wish they had two grub screws instead of just one.

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.

These are nice fit my ender 3. I do recommend adding some loctite to the set scew or it will come loose everytime

Bought these for my 3d printer and they work better than the stock ones! Holds the tubing well and tight! Happy with them.
