C-clip wrapping a vertical pipe F · F3 · f3-clip-pipe-01

Prompt

Reference images of a vertical pipe (16mm OD, 30mm tall) are attached. Design a C-clip that wraps around the pipe at mid-height with a radial slot opening to the +X side. The slot must be narrower than the pipe diameter so the clip is form-locked: pulling the clip in the -X direction would force the slot edges to spread, which they cannot (the clip is rigid).

Requirements:
- Single solid, single-root .vcad.
- The clip's internal bore must clear the 16mm pipe with 0.1–0.5mm radial clearance (so an internal diameter of 16.2–17.0mm).
- The slot (opening on +X) must be no more than 4mm wide in the Y direction. The slot opens to the +X side and extends from the bore radially outward to the clip's outer surface.
- The clip's outer diameter must be ≤ 26mm.
- The clip's height (Z extent) must be 8–12mm.
- Wall thickness everywhere ≥ 1.5mm.

Output the clip in the host frame: pipe axis +Z, pipe base at z=0, pipe top at z=30. Place the clip at z roughly 10..20 (mid-height of the pipe), centred on the pipe's axis in X/Y.
