Collapsing Cube Moldmaking Studies

I've been studying certain sizes and shapes of collapsing cubes and assessing a method of pattern development of an armature to be built up in styro-foam.



Starting at a size that will be five feet on each side, I've decided to convert to millimeters for simplicity as opposed to using fractions.



Intersecting this cube with a radius of thirteen feet I've come up with the above as a derivative that is one-eighth of a cube for mold-making purposes.
