Mastermind with icons

This is a remake of the famous game MASTERMIND
https://en.wikipedia.org/wiki/Mastermind_(board_game)

Instead of different colored pins, this version requires only one color.
Every pin has an icon.

Print mastermind.stl
Optionally print mastermind_bottom.stl (the bottom part for the case)
Print as many pins as you want!
I use the *circle* as black pin and *circle_check* as white pin. And six of the other pins. (cloud, heart, triangle, square, moon and fower)
