This is a tray for Tiny Towns to hold your resource cubes. Print 5 of them, one for each color resource. The slot for the resources is actually narrower at the bottom, hence the reason the trays are a bit loose at the top.

I REALLY hate my resource cubes being all mixed together, so I found myself sorting them each time we played. These trays work really well to keep them sorted.

The peg in the middle is so you can pull them out of the storage slot. Notice in the picture that with all five stacked in the box, it just reaches the top, keeping the cubes neatly in the trays.
