This is a torus composed of 5 circular strips tilted at 30 degrees to an axis, then rotated around that central axis. 5 more strips, mirror images of the first set, intersect the first set, and are rotated around the same axis.Each strip twists a full 360 degrees as it completes the circle, keeping its long axis perpendicular to the surface of the torus. The strips are centered on Villarceau circles, which are those resulting from a hollow torus cut by a plane parallel to both the top and bottom surfaces of the torus. The strips are 1.5 mm thick by 3 mm wide, to print in metallic plastic..
