Calibration and quest cube

Calibration and quest cube

I created this cube model for several reasons:

1. I used to ask my students to design a solid that could pass through the three type of holes of this figure. The side of the cube is equal to the diameter of the cyrcle and equal to the base and hight of the triangule. The idea is to make them think about solid forms.

Normaly I have this model made of transparency films sheets or card board. But now with my TT I will finally have it the way I always wanted.
