Final solidworks model
To make use of the space inside, a diamond shape is put in. Circular cut outs are put in the middle of the six faces of the cube, corresponding, and holding in place, the six corners of the diamond shape. The surface of the diamond is left untouched, so the pattern on the cube can be projected clearly on its surfaces under the right light, as explored with my second solidwork model. Two of the faces of the cube is also left without pattern on it, with the idea that they will act as windows into the interior of the form, allowing a glimspse of the connections and shape inside.
