Customizable Mobius Ring

Congratulation to me, I'm making an eternity ring! In my experiments I tried a variety of shapes, each is swept around a major axis while twisting round the minor axis. Now you can try these too! Click 'Open in Customizer' and play: try changing the cross-section shape from triangle, ellipse to a [Reuleaux Triangle](https://en.wikipedia.org/wiki/Reuleaux_triangle) (a curve of constant width which looks like a rounded triangle), and adjust the other dimensions too.

Note: If Thingiverse can't render this, please try downloading OpenSCAD, download mobius_ring.scad from Thing Files and experiment with it there.
