Is a Dice Tower, you can pause the print to make it black, then white and then black again.

If you have one dice, the exit of the dice can exit in 6 boxes with the sam probability so is used as an result.

To use it just throw the dice in the upper hole and see where it drops.

If you want me to adjust something just write a comment. Thanks!

PD: Added the dots and the numbers if ypu want to print and glue.
