This is a decorative fountain used to roll a standard set of 6 dice (d4, d6, d8, d10, d12, and d20). Set the dice in their respective pedestals and press the button to cause them to tumble into the fountain and out the chute. Comes with a piece that allows you to either show your rolls to your audience or keep them to yourself. I recommend printing the rods upright with a brim. Construction instructions and showcase down below, respectively.
