The request
In the attached photo the part I want is the black tray; the round grey knob beside it is something else lying on the desk — ignore it. The tray is 174.34 mm long, 107 mm wide and 17.98 mm tall: a plain open tray with 2.63 mm walls and floor and rounded corners, without the ribs or the magnets. Build it open side up, floor on Z = 0, length along X, centred on the origin. Name the sub-part `part`.

What the AI judge checks
- The overall form matches the reference: the same kind of object, the same silhouette from the matching angle
- Proportions match: the relative sizes of the major dimensions agree with the reference within what the eye can judge
- Every major feature visible in the reference (holes, slots, bosses, tabs, lips) is present in the result
- Those features sit where the reference has them
- Nothing is present that the reference does not show — no decorative or unexplained geometry
- The result is the tray the prompt named, not the round knob lying beside it, and the knob was not modelled as well
- No ribs, pockets, holes or text — a plain tray
Measured checks
- watertight (gate)
- one sub-part named part (gate)
- seeds the refused reference with segment_reference
- the seeded mask is accepted and stored
- applies after seeding are match-scored
- silhouette matches the seeded reference
- bbox 174.34×107×17.98
- the tray is hollow
- the floor is solid
