Dice and marble storage tray for board games (like Aggravation)

This dice/marble storage tray was designed as a replacement for my family's Aggravation board game from the early 70's. It might be useful for other games that use dice and/or marbles.

Holds 12 standard dice and 24 marbles, in 6 rows of 4. Our Aggravation marbles are about 14.5 mm diameter, and the tray should hold up to 14.75 mm diameter marbles, 4 per row, without modification. You should be able to scale the model in your slicer to accommodate more and/or different sized marbles.
