Photo lid

The request

The attached photo shows the inside of a plastic case lid from straight above. It is 174.34 mm long and 17.98 mm tall overall, with 2.63 mm walls and floor, and a grid of 0.75 mm ribs standing 2.25 mm above the floor. Make one that matches the picture: the outline, the rib grid exactly as the photo shows it, and the cut-off inner corners each with a 4 mm round magnet pocket. Build it open side up — the floor's outer face on Z = 0, length along X, width along Y, centred on the origin, laid out as the photo shows it seen from +Z. Name the sub-part `lid`.

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
• Each inner corner is cut off diagonally and carries one small round pocket
• An open tray whose walls stand well above the rib grid, with no lid, cover or ribs reaching the rim
