Rock Tumbler using an old fan motor

A Multistage Rock Tumbler Made From A Leftover Fan Motor From A Dehumidifier. Bearing Blocks And Pulleys Are 3D Printed. The Belt Is A Big O-Ring. The Tumbling Barrel Are Recyclable Containers. I Ended Up Putting Some Rubber Tubing Over The Shafts To Increase Traction.
