Rummikub Tray - Stackable

This is a tray for Rummikub - a tile-based rummy game. The trays the game came with make a terrible screeching sound when moving around on my table, so I went on designing a tray that would fit the tiles without falling out, still being visible on each level, and having a 4th level to easily separate each color (suit). I made them slightly interlock so that they don't slide around in the box.I printed with a .6mm hotend, bambu pla, 10% lightning infil with 3 wall loops.
