Coin dice + storage box

Set of dice - piece with storage box.

Freely inspired by [this](https://www.thingiverse.com/thing:5576934) and [that](https://www.thingiverse.com/thing:5546384). I found it impractical to read from the edge, so it is read from the top.

I used 2.45 mm diameter ball bearings from 13x5x4 mm bearings.

For each die, print the two files (a and b) with the numbers on the bed. Use the smallest layer height so the inner cone has the most steps. The tower is designed smooth but on the pictures it was printed with fuzzy skin (0,1 mm deep).

Depending on the printer settings, it should fit via press fit. I still used a little glue on the protrusions.

I tested the dice during a role-playing game evening, and they work as is, although I may make some modifications after further testing or feedback from other users.
