Coin spinner

This is a slightly modified version of the [Money Spinner](https://www.thingiverse.com/thing:1937473) by GeoffB. I had a lot of 20 euro cent coins lying around, and wanted to use those. This is a good way to put some copper coins you have lying around since your last trip to use.

Instead of selecting from a short list of coins, now you have to put in the size of your favourite coin directly. Look it up at Wikipedia, do a web search, or use a calliper. The pre-set size is for 20 euro cent coins. For the centre, you have to use a 608-sized bearing, i.e. 8 mm × 22 mm × 7 mm.

When you use euro coins, you can make yours a symbol of international cooperation. Mine is now using coins from

* France
* Greece
* Ireland
* Italy
* Portugal
* Slovenia
* Austria
* Germany
* the Netherlands

Nine coins, nine countries! The last three are on the inside.

I also added the bearing caps from Arondite’s [Fidget Toy Comfort Spinner](https://www.thingiverse.com/thing:1816684)
