It's an insert for the boardgame Fairy Ring, I liked the one that came with it, but it didn't have enough space for sleeved cards, so I've made this one.

I've also changed the design a little bit from the pictures to be able to store the game vertically (haven't tested it though).

It's important to mention, the box isn't a perfect square, it's 1mm bigger in one of the sides, so if the insert isn't fitting, just try rotating everything.

To build it you'll need to print: 1x Cards 0 2x Cards 1 and 2 1x Objectives 1x Fairies Left 1x Fairies Right 2x Points 1x Spinner
