Simple D20 three step dice roller

This model tries to solve three main objectives:

1. A small dice rolling tower
2. Can be be rolled again quickly without a lot of effort 
3. Has that a good tower rolling sound

I hope that his model is as fun to use as my many hours using it a desktop fidget toy.

Please note: I've listed it as a D20 roller because that seems to be the only dice that constantly rolls on the model.
