Inspired by the metal / alloy Turner's Cubes you often see on the internet, I wanted to 3D print my own. Rather than downloading a previously made design, I put in the effort to make the CAD file from scratch, this gave me the control to customize the dimensions and inner details. The premise was simple, I wanted 3 pieces (small, medium, large cube), with the two inner ones impossible to take out, but completely moveable inside of one another. The project was modeled in NURBS and I used reference material from engineering websites for the proportions and dimensions of the cube.
Of course, a fully moveable plastic Turner’s Cube would have to be printed with supports. So support material was used for the two inner cubes, while the largest and most outer one was printed flat on the print bed.
