This dice tray is shaped for the d20 and associated dice included with many tabletop RPG's. It allows every dice to lay flat with its number facing up. Each hex is labeled for the dice that belongs there. No supports are required for this print.
The dice tray is 9mm tall. For a two color effect, switch to a different filament color at the 7.5mm mark.
