Spinning fidget coin (with btc and eth logo)

Spinning coins!

This is my first model, so it is probably far from perfect.

The coin spins perfectly inside (especially after playing with it a bit).

How to print a coin?

To successfully print a coin:

1. First print the inner coin
2. Then print the ring
3. When the print of the ring pauses (layer 17), add the inner coin: the top face down (see photo below – otherwise the nozzle might hit the top layer)
4. Resume the print

A few advice

You can add/remove any logo on both sides for the coin and I advice only the top side for the ring (otherwise it might weaken the connection).

If you want to reduce the model, do not reduce the z direction, it would be too weak, only x and y. Current size is 5cm*5cm.
