Photo lid then centred

The requests, in order
1The attached photo shows the inside of a plastic case lid from above, though not squarely — the camera is off to one side and a cutting mat is in frame. The lid 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. Name the sub-part `lid`.
2Here is a straight-on shot of the same lid from directly above. Use it to check the outline and proportions, and fix anything that is off.

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
