Customizable Keychain Dice Spinner

Prints in place, die rotates freely inside the disk.

* Text on the die is fully customizable!
* You can also paste (some) unicode symbols like ☺ (see note below)
* Hanger shape, disk shape and chamfer can be customized as well.

You can copy unicode symbols for example from here:
https://en.wikipedia.org/wiki/List_of_Unicode_characters#Miscellaneous_Symbols

**Note for unicode symbols:** The font selection in thingiverse customizer seems broken, the default font always seems to be used. If you use OpenScad customizer on your PC you should be able to use all symbols when selecting the Segoe UI Symbols font.

**Note about numbers on die faces:** Text parameters also seem broken in customizer. A number is not accepted as text. If you want to use a single digit like "3" you have to add a space before and after it " 3 ".

**Update v02a**
- Cleaned up minor issue with the hanger hole
- Added font and style selection in customizer, works on PC but not on thingiverse.
