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

Purchased BIQU Extruder Pulley 36Teeth Bore 5mm Stainless Steel Drive Gear for 1.75mm & 3mm 3D Printer Filament (Pack of 5pcs) for 3D printer upgrade. Gears are made of high-quality stainless steel and are a direct fit replacement for Flashforge Adventurer Series 3D printers. Highly recommended!

The original that came with the printer is too cheap and bad. My printer stopped extruding everytime because of them. With these my problem went away. I replace them in an Ender 3 v2

I have used these on every 3D printer I own or have owned. I dont even bother with stock gears anymore, as soon as I open a new printer I find the extruder and replace the brass gear with one of these. Absolutely no complaints.

Collar is ferric stainless, actual spurs are austentic stainless. For those of you who are trying to confirm these are indeed steel via magnetism. These are indeed stainless steel. Just the spurs are austentic stainless (non magnetic) with a higher chromium content than that of the collar. Otherwise the spurs grip filament nicely.

These have worked well over the past prints! The teeth come to a more defined point so they grab the filament better and wont slip. Wont wear out like the cheap brass ones.

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

Worked good on my cr-10s

I got this as an upgrade to my CR-10S, which seems to work a lot better than the factory brass one. After installation all you have to do is calibrate your E-Steps, which I used a video by SanTube 3D off YouTube to explain the process. Afterwards I would suggest re-flashing the firmware with the new calculation of your E-Steps as some printers may vary, so you wont have to keep putting the E-Steps in every time when you turn off or restart your printer.

Good choice. Same size as the original on my extruder so I didnt have to mess with resetting the e-steps. Well built and like the 2 set screws to keep things locked up.

These work great in my ender 3
