Hedgehog or Hamster Bearing Training Wheel

thingiverse

I designed this Hedgehog wheel for my daughter, and it requires these parts to complete: 1 x 150mm long threaded rod, 6mm in diameter. 2 x 626 Z bearings (18.8mm outer diameter, 6mm inner diameter, about 6mm thick). 7 x 6mm nuts. 2 x 6mm washers. To assemble it, you'll insert a spacer between the two bearings and secure it with the nuts. Don't forget to add a washer between the wheel and stand as well. I used two nuts on either side of the shaft/threaded rod to keep everything locked in place.
