Generates three equal parts that form a cube. Reverse engineered from Erikjuh's model, reverse engineered from "Cubic Trisection", invented by Robert Reid and designed by Oskar van Deventer.

In addition to customizing the size, tolerance, and fineness, you can change the twist and offset of the spiral. By default it uses the same angles as Erikjuh's model: `240, -60`.
