Configurable-fit ring with customizable orthogonal-line pattern

This is a simple, smooth band with any number of horizontal or vertical surface cuts for decoration. Configurable features, besides the pattern of cuts, include the ring's size (in US/Canada measures by default, although that's modifiable), the ring's thickness at its widest point, its exterior bulginess (for a "domed" rather than flat face), interior bulginess (for "comfort fit", as it's often called), and the style of the decorative incisions.

UPDATE 22 JAN 2020: It now features three different styles of decorative engraving (rounded, diamond, and now square), and has more intelligent angling of the engraving to always be perpendicular to the ring's surface (instead of perpendicular to the ring's central axis, which if the ring's outside surface is domed, isn't the same thing).
