Player Tile holder for "Brass" (boardgame)

thingiverse

Each player has 5 piles of tiles to manage during a game of Brass, and it's usually me who ends up knocking mine over at some point. Players like myself need a tile holder that can withstand accidental nudges and keep our tiles organized as well. The free-standing side arms on the corners of the tile holder are more fragile than I prefer. They would benefit from additional bracing along the sides to increase their strength, as only one face needs to be open for players to draw out chits.
