Welcome to the community!
The original design was referenced in this post:
It was a design posted by someone else. It was so unique I knew I wanted to give it a try! I didn’t like everything about it so I did make a few a changes for my version, but it turned out beautiful!
Now that it is done, if/when I do it again I would make more changes to the box. (Mainly I would probably build in a drawer for the tokens and make sure it is big enough to hold the expansion.)
