I wanted a tray to use with a dice tower I printed to prevent the dice from going all over the place.
The dice tower is this one https://www.printables.com/model/343681-segmented-dice-tower-v3 - which is 96mm in diameter.
Nothing special is required to print - I used lightning infill to save on filament.
The author remixed this model.
This model is scaled up to fit the 96mm diameter of this dice tower: https://www.printables.com/model/343681-segmented-dice-tower-v3/comments
