Dice Tower

I had an idea to make a device that doesn't allow to predict a dice throw. I wanted to created something compact that could allow to throw from d4 to d20. And it is out now!

Let me introduce a foldable tower. It consists of following parts: steps (default 12pcs.), a base with catchers, an axis for stability. Axis 3d model works for 12 step tower.
You can print out as many steps as you want, just keep in mind that steps without axis are pretty unstable. So you need to modify the axis and make it longer. Or ask me, I can fix it for you.

Every step has 2 sides: plain and steppy type. I would recommend connect steps with same type of stairs at the same side so you get correct type of stairs.
Steps have fixed click-positions: for folded and expanded positions.

Print time for 3 steps at once takes about 6 hours.
