Hamster Spinning Wheel From Ikea Plate

I made this hamster spinning wheel from an Ikea plate, 3D printed parts, a carriage bolt and a bearing from an old fidget spinner.

Our hamster runs 4.5 km a night

I printed the base in PLA with an 0.8 mm nozzle on my Wanhao Duplicator i3. Assemble the base with 2 screws. The bearing should fit in precisely.

Drill a hole in the plate of 8 mm. Cut it square with a knife, so the 8 mm carriage bolt fits in fine.

The plate is separated from the bearing by a 3D printed ring.

Assemble the wheel by mounting the bolt and fix it with a nut.

If the wheel spins too fast, you can slow it down by fastening a tie wrap around the separation ring, so that it makes contact with the bearing.

You can fix in the cage by using some rubber adhesive footpads.
