Sushi Go Party Insert

Boardgame insert for [Sushi Go Party](https://boardgamegeek.com/boardgame/192291/sushi-go-party)

Inspired by [https://www.thingiverse.com/thing:3144641](https://www.thingiverse.com/thing:3144641). I created my own because for some reason, my tin seems to be shorter. So to fit the board and rules in, I had to lower the height and slant the walls.
