This is a clever dice rolling machine designed and assembled by The Karakuri Channel from 3D printed parts. When USB powered, it’s capable of rolling two mini dice over and over, collecting the dice after a roll, sending them up an elevator, and rerolling (complete with two rings that descend to prevent the dice from rolling off the table). That’s pretty incredible. But is it even a valid roll if you don’t blow on the dice first and yell, “Come on, baby, daddy needs a new pair of shoes!” I would argue not.
