Skate Pulley Set

thingiverse

A set of four pulleys is available, each with varying diameters ranging from 2.5 inches to 10 inches and all are 1/4 inch thick. The largest 10-inch pulley requires a quarter section, but in reality, you need four of them to complete one pulley. Furthermore, it demands hardware to be assembled together along with a 6 mm motor coupler. In contrast, the three smaller pulleys are engineered to fit into an 8 x 22 x 7 mm skate bearing snugly. It's worth noting that depending on the specific bearing used, the center hole might need to be enlarged by one-sixteenth of an inch so it doesn't come into contact with the bearing collar.
