This is a personal project I undertook because I wanted to practice my skills on the manual mill. The first time I went into the machine shop I misjudged the distance that I needed to plunge to create the cube-with-cube illusion resulting in a slight failure. The next time I attempted to complete the project I went in with an understanding of the measurements I needed to enforce so the cube was completed without much trouble. In the future I want to try and make a turner's cube that has a free cube within a cube.
