Watch Box Kit - Box, Frame Lid, 3x3 Divider, 2 Hinges (Exploded)

Create a simple, professional, parametric, 3D-printable watch box. All dimensions are in millimeters. **Overall dimensions:** 205 mm wide × 260 mm long × 115 mm total closed height. Create these separate, manually assemblable parts: 1. **Bottom box:** Open-top rectangular box, 3 mm walls and 3 mm bottom. 2. **Lid:** Separate rectangular frame with an empty center. Add a continuous 2–3 mm deep ledge on the underside of the opening so a separately cut acrylic sheet can rest on it. Do not include the acrylic. 3. **Divider insert:** One single, rigid, removable 3 × 3 grid, not separate divider panels. Target clear compartment dimensions: 60 × 75 mm each, approximately 2 mm divider thickness. It must fit inside the box and be removable by hand without tools or glue. 4. **Hinges:** Separate components connecting the lid and box. Prefer standard metal hinges with suitable mounting holes. **Manufacturing requirements:** Design for FDM 3D printing with a 0.4 mm nozzle. Use practical clearances of approximately 0.3–0.5 mm for fitting parts. Keep geometry simple, strong, and easy to print. **Critical:** Preserve all specified dimensions wherever geometrically possible. Verify the compartment sizes, insert fit, lid fit, acrylic ledge, hinge alignment, and 115 mm closed height. If dimensions conflict, report the conflict rather than silently changing them. **Export:** Provide separate STL files for the box, lid, one-piece divider insert, and any custom hinge parts. Provide a STEP assembly if supported. Include a simple exploded view showing how the parts fit together. Do not add unnecessary mechanisms or decorative details.
