description The Marching Cubes algorithm was used so that the model formed was watertight, and so could be 3D printed - a simple stack of extruded 2D frames could have caused problems with some 3d printer slicer software packages. This particular model was a bit challenging as a 3D print, as the walls are quite thin at places.

Not everything that can be modeled can be 3D printed, there are design guidelines giving general rules for wall and wire thicknesses.
