The prompt
Create a precise, solid, FDM-printable CAD model of a premium 9-compartment watch box bottom. All dimensions in mm. **Dimensions:** Exterior 241×241×80; interior cavity 232×232×75.5; wall and floor thickness 4.5. Cavity height is measured from the floor's top surface to the top rim. Exterior height must remain exactly 80. **Interior:** All interior corners and floor-to-wall transitions must be sharp 90° angles. Flat floor and perpendicular walls. No internal fillets, chamfers, ribs, grooves, steps or protrusions. Exterior corners may have 6 mm radii, without affecting interior geometry or dimensions. Never round all edges globally. **Dividers:** Four separate, removable, interlocking dividers form a 3×3 grid, assembled outside and inserted together. Each is 232×45×3.5 mm; two Type A and two Type B with compatible slots. No integrated walls, floor slots, rails, glue channels, hooks or snap-fits. Dividers rest directly on the floor. **Compartments:** Exactly nine identical 75×75 mm clear footprints before lining. Calculation: 3×75 + 2×3.5 = 232. Divider centerlines at 76.75 and 155.25 mm from each corresponding interior wall. **Lid:** Separate lid, 241×241×30 mm. Provide a flat, continuous top rim and two reinforced rear mounting areas for external metal hinges. No printed hinges; do not finalize screw holes before hinge dimensions are known. Ensure collision-free opening and closing. **Style and printability:** Minimalist, flat exterior walls, consistent thickness, no logos, text or unnecessary holes. Watertight manifold solid; no self-intersections, non-manifold edges, zero-thickness surfaces, unintended cavities or altered wall thickness. **Output:** Export only `watch_box_bottom.stl`. Verify all dimensions, sharp interior corners, divider fit and nine compartment sizes before claiming successful validation. Do not claim checks that were not performed.
