Dungeons & Dragons dice mount, tray, and inserts

I designed this three-piece accessory to keep my game sessions organized. The main piece is a rolling tray with designated mounts for each die, with labels for d4, d6, d8, and so on—so everyone always knows which dice go where. Along with the tray, there are two additional inserts: one adds an extra dice mount for those with more than one set, and the other provides a split storage space for small items like a player miniature, a dice jail for any stray dice, or similar bits.
