Motor pulley for N20 motor with metal gears

thingiverse

This pulley is designed for N20 motors and requires an M3 nut and a 5mm-long M3 bolt to secure it onto the motor shaft. I've included FreeCAD files that you can modify as needed, allowing you to remix the design according to your preferences. To assemble the pulley correctly, simply follow the clear instructions in the accompanying video at https://www.youtube.com/watch?v=A8iI0b6D280.
