Configurable-fit ring with customizable orthogonal-line pattern

thingiverse

This is a basic, streamlined band with multiple horizontal or vertical surface cuts for ornamentation. Customizable features, beyond the pattern of cuts, include the ring's size (in US/Canada measurements by default, although that can be adjusted), its maximum thickness at its widest point, exterior fullness (for a "domed" rather than flat face), interior fullness (for "comfort fit", as it is often referred to), and the style of decorative incisions. UPDATE 22 JAN 2020: It now includes three different styles of decorative engraving (rounded, diamond, and square), and has more intelligent angling of the engraving always 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).
