Summary

Create and customize a bracelet using the power of trigonometry. Take that, precalculus students who ask "when are we ever gonna use this?"!

Use the Customizer to design a bracelet that fits your unique size and style. This file is the master code that built the following previous models:
TRI: www.thingiverse.com/thing:416336
SUN: www.thingiverse.com/thing:425503
RIB: www.thingiverse.com/thing:425784
POW: www.thingiverse.com/thing:426034

With this more general code you can do much more, including making oval instead of round bracelets, open wrap bracelets instead of circular bangles, and many additional trigonometric and design variations.

This is great, exactly what I needed for a new project.
I was confused by "thickness" since I thought that would be the width of the generated bracelet. The width of the bracelet generated is 2xthickness, since this is used as a radius in the function.
