Hamster wheel

Updated! Now two sizes: 20 cm and 15 cm.

Hamster wheel. Very quiet by using a double set of bearings.

The assembly consists of 8 parts, of which several of each must be printed: Part-1 (3 pieces), Part-2 (6 pieces), Part-3 (2 pieces), Part-4 (2 pieces), Part-5 (2 pieces), Part-6 (2 pieces), Part-7 (2 pieces), Part-8 (4 pieces). The wheel is fragmented so that it can be printed on any printer. The parts have clearance so they will always fit. You also need 4 bearings (13 mm outside diameter, 6 mm inside diameter and 5 mm wide. They are very cheap, I bought 10 for 1,2€), 4 metric 6 nuts, 4 metric 6 washers and a piece of 110 mm metric 6 threaded rod. The cost of all the unprinted parts should be about 1,5€. I also used glue to join the parts (I used two component Epoxy). Finally, to regulate the speed, tighten the nuts more or less.

The 15 cm version has the same instructions and quantities, but its parts 1, 2, 3, 4 are model B.

If you are interested in improvements or more sizes, comment the design or send me an email!

P.S. There is a difference between the images and the STL: The wooden slats, my hamster was skidding because it was smooth and I glued wooden slats, the 3D is already updated!

Use white PLA, with a density of 20%. Total printing time approx. 30 hours.
