This was made as a gift for my brother who plays Azul. It sits on top of a standard Azul board and aligns the tiles to make it more satisfying, and so I spend less time fidgeting with the alignment of the tiles. Made in Fusion 360. I printed mine in transparent PETG on a Prusa Mini, also with an extrusion multiplier of .98 which seemed to fix a lot of first layer issues for me with this specific filament.
