Magnetic Setting Stackable Dice
by Ssmigielski, published
Prototype Idea while I wait for my 3d printer,
a 12mm 6 sided "countdown" dice with 1/8x1/32 in insets in each face for rare earth magnets to make it easier to store/stack sets.
Sketchup file included.
Have not printed yet, so other people's expert advice welcome.
