Z-axis Drive Pulley 3D Printed
I had a stepper motor and matching belt pulled from a surplus printer that fit the Z-axis bracket, but did not have the matching pulley. The belt is a 1.5mm pitch, which has tiny teeth. 1.5mm pitch pulleys are also not readily available, so I modeled one in Solidworks and printed it out on my 3D printer. I was unsure of how the teeth would resolve due to their tiny size, and the resolution of the printer. The printed part turned out to be functional. The teeth are rounded quite a bit, but the belt still engaged properly.
