Cable clip

The request

Make a parametric cable clip, Z up: a flat base plate 20 mm along X, 6 mm along Y and 2 mm thick, centred on the origin in X and Y with its bottom face on Z = 0. Standing on it is a ring 6 mm long along Y whose axis runs along Y, with an inside diameter of `cable` + 0.4 mm and a 2 mm wall. The ring's centre sits at Z = 2 + `cable`/2 + 1.4, which sinks the bottom of the ring 0.8 mm into the plate. The ring is open at the top: cut a slot straight up from the height of the ring's centre, 25 percent narrower than the cable (0.75 x `cable` wide), so the cable pushes past the lips and is held. Expose one control named exactly `cable` (cable diameter, 4 to 14 mm, step 0.5, default 8). Name the sub-part exactly `clip`.

What the AI judge checks

• A small flat base plate
• A C-shaped ring standing on the plate, open at the top
• The opening at the top is visibly narrower than the ring's inside
• Nothing else was added

Measured checks

• one sub-part named clip (gate)
• cable is exposed as 4 to 14 (gate)
• base plate is 20 x 6 and sits on Z = 0
• the ring's bore is the cable plus 0.4 mm
• the opening is 25 percent narrower than the cable
