Mendel Pulleys

thingiverse

Mendel pulleys, featuring an M3 grub screw and captive nut, offer an advantage over originals as they only require one small flat on the motor shaft instead of two full-length ones that need precise filing. Suitable for all three axes, these pulleys can be reamed to 5mm and 3.5mm before fitting the nut and grub screw. For best results, print three simultaneously to prevent overheating, while machines with oozing may call for individual printing to avoid string formation.
