Annular snap-fit generator

Generate a parametric annular snap-fit (beaded plug + receiving ring)

The round sibling of the cantilever snap: a post carrying a raised bead near its tip, and a receiving ring whose bore is narrower than the bead with an internal groove behind it. Push it through and the bead springs into the groove — the joint used for pen caps, bottle caps and round enclosures. Retention is purely geometric, and both parts print flat.
