3-in-1 Box (7 Wonders Duel, Splendor Duel, KingDomino)

A friend wanted to be able to easily transport these 3 games, so he asked me to design an insert that would work. Everything fits in the 7 Wonders Duel box. You can do supports on the coin holder if you like, but none needed on the main piece.

The coin holder is a remix of another model that can be found here - https://www.thingiverse.com/thing:4655718
