Case that can hold tokens/coins with cutout for viewing and twist-top lid. Designed for and holds 15 Axolotl coins (40mm diameter, 5mm height) https://www.prusaprinters.org/prints/112299-axolotl-coin-minecraft-inspired. Should work for any types of coins or tokens ~30-40mm in diameter or anything else that won't slide out of the view cutout. 

I have printed with no supports on my Prusa Mini+, but there can be some sag in the bridge at the top of the view cutout if you don't use supports.
