These are tile holders for Azul. They are used to organize the board while playing the game.The accessories for Pandemic: The Cure served as the conceptual idea for this.
There are two versions of the Center Ring:
- One that prints as a single part (for those with larger print beds).
- One that is split into four parts that snap together to form the Ring.
You need to print nine Factory Ring. Should you use the split Center Ring, you need to print four of those.
For nine rings, you'll get a perfect angle between the rings. For five, and seven, you'll not get perfect angles. But, it looks good enough.
Should you want a laser cut version, you'll find it here.
If you can't print it yourself, you can buy a one here.
