Large Hamster Wheel

I have a fairly large hedgehog and the small hamster wheels are just not wide enough for her needs. My 3D printer is small and I had to make it out of 3 pieces.

You must print this much:

- center piece (x2)
- corner piece (x2)
- side piece (x10)

Please try to print them standing up, minimising the need for support material in crucial places, at bindings.
