Enneper's surface, with 3 lobes, converted into a mesh. This is a minimal surface, like a soap bubble. (Imagine that the perimeter is formed of wire, then dip it into a soap solution.) It is particularly elegant in silver. To make it more delicate, the diameter of the wires is only .7 mm, so this model is not printable in steel or the polished metals. The equation is trigonometric, plotted in Mathematica, thickened in MeshLab. Findings are not included.
