Customizable Ring Thing

This is a simple customizable thing that consists, essentially, of a number of rings equally spaced radially around an axis. That dry-sounding mathematical description yields a number of intresting and useful forms, including napkin rings, bracelets, bowls, domed cage-like things, etc. Some interesting and possibly even useful examples are included as pre-made STL files, or just fiddle around with the controls until you get something you like.

The customizable parameters are as follows:
**Number Of Rings** -- this is, unsurprisingly, the total number of rings generated. More rings makes for more dense things, fewer rings produce a more open lattice effect.
**Ring Radius** -- this is the overall radius (i.e. major radius) of the rings; it controls the overall scale of your thing.
**Ring Thickness** -- this controls the "chunkiness" of your thing (more precisely, it's the minor radius of the rings).
**X Rotation** -- this controls the uprightness of the thing and the angle of t
