This is a torus bracelet formed of 12 touching Mobius strips, every one interlinked with every other one. The twist allows you to see inside the torus, while the strips remain connected. This version puts the long axis of the strips perpendicular to the outside surface of the torus, and parallel to the inside surface. The inside diameter is 70mm (2.76"); if you need a different size, let me know: it is easy to adjust the model, or to make a larger torus that is not a bracelet.
