Billiard tokens

I made this design a few years ago. I have a billiard table and an air hockey table at home that I bought from an arcade that closed down. The games work with these tokens, overriding the system seemed complicated, and I always lost the tokens, so I decided to make my own. They work with other things too, like fairground rides and other types of arcade games. If you need to modify them to fit your games, feel free to do so.
