Hamster Wheel with 608ZZ bearings

thingiverse

This is a hamster wheel I designed, it's really simple to print and assemble, with only 4 printed parts that you'll need to put together along with some nuts and bolts listed below: - 4x wood screw 3*15L - 1x M8 threaded rod 90mm long - 3x M8 nut - 2x speed ring - 1x 8mm ID and 11mm long spacer (between the bearings) I filled the sockets where the M8 rod rests with some epoxy to keep it in place. - The assembly of the base is pretty straightforward. - Press the bearings into the wheel with the 11mm spacer between them. - Slide the rod through the bearings, put one nut and one speedring at the closed side of the wheel, leaving about 10mm sticking out from the nut. - Put another speedring on the rod on the open side of the wheel, then add two nuts that lock each other in place. You could also use one nut and loctite instead. - You're done! Just put the two ends of the rod into the socket on the vertical stands and glue them in place so they can't move.
