NOTE: OBSOLETE

The designs below use OpenJSCAD V1 which has long been superceded by the incompatible V2 API. Links are to a kindly-provided V1 host that may not stick around forever, in which case V1 -> V2 migration guide may come in handy.

Also references/links are made to a Google+ community and posts, all of which were et by the Google+ turndown.

Tapered text

Prompted by a G+ post I hacked up a demo of tapered text
