Dice Tower (1st prototype attempt)

Finally the construction of dice tower is completed! This is how the dice tower look like:

The material I chose was thin layered styrofoam (cost Rp.36.000,00/board - about 3 USD). This material is light, easy to cut but sturdy enough to hold the construction.
There's only one mechanic to shake the die. It is a small diagonal board at the back of construction. This board not only act as shaking-mechanic but also to make sure the dice will appear at the front side.

During test phase, unfortunately the material proves to be too light and make the dice tower jump around when casting a rather heavy dice. The front-side, area for the die to appear, also proves to be too narrow. In some cases die will jump out from there >.<. I think I will change the construction a bit to overcome these two problems. I'll post a new design and prototype when I'm done with them.
Again, thank you so much for reading this post ^^.
