Hopf fibration pendant

The easiest way to understand this model of the Hopf fibration (actually 2 of them, crossing one another at right angles) may be to see it as a torus surface being turned inside-out through a hole in its side. The structure is entirely composed of circles, or arcs of them, forming a deformed grid on the torus. The pendant chain is not included.It has been resized to 1.5 mm diameter wires to print in metallic plastic.
