Directional dice tower that can output dice in two different directions based on adjustable flipper in the base of the tower. Print as many tower pieces as you'd like to make the tower taller.

You'll need small circular magnets, 4mm radius and 1mm thickness. They are really cheap on ebay and amazon.

Added another type of tower piece that has a different kind of dice agitator. Should be compatible with the other type.
