Challenge Coin Stand
This is a quick print of a stand that I made for a coin with a rotating center.  It is very customizable and works well with common round coins as well.  I’ve included a few variations on separate plate.  The only setting to watch out for is where the seam is placed.  In the project, it is set to the back.

The base\coin diameter, number of sides, rotation of the coin, and the deepness of it cut out is constant in this project, but variable in my design.  I recommend using one as close to your coins thickness so that rests at a more secure 5-degree relief.  Feel free to remix or let me know if I can make adjustments to fit yours.  I’m happy to do so.
 

This Wikipedia article is worth a skim.  [https://en.wikipedia.org/wiki/Challenge_coin](https://en.wikipedia.org/wiki/Challenge_coin). There is a diverse tradition and culture in challenge coins.  
Whatever the circumstance, I hope yours is a proud and positive reflection.
