Bicycle Chain Pulley

This is a pulley that I made for Cal Poly Pomona's Human Powered Vehicle. It may be of no use to you since it is a very niche item, but I thought it would be cool to let people print it out and play with it. Think of it as a fidget toy, as it does use the same sized skateboard bearings. You may want to glue the two halves of the pulley together so that the parts don't come apart, but if it is not under load you can leave them as is.

Note: In Cura 2.x.x, I have not figured out how to split it
