The prompt

## 4. 3D Printing and Modular Hull Construction The vessel must be designed specifically for a 3D printer with a maximum build volume of 270 × 270 × 270 mm. - Divide the 1200 mm long hull into multiple printable modules. - No individual printed part may exceed 270 × 270 × 270 mm in any dimension. - Divide the hull into practical longitudinal sections while preserving the vessel's original shape and structural strength. - Design strong mechanical alignment joints between all hull sections. - Include interlocking connection features, internal reinforcement ribs and screw or bolt mounting points. - Make the modules easy to assemble, disassemble and seal against water leakage. - Avoid unnecessary seams and complicated assembly procedures. - Design the deck, raised bow structure, stern platform and other large components as separate printable parts where necessary. - Ensure every component is correctly oriented and suitable for FDM 3D printing. - Provide separate STL files for every printable component. - Also provide a complete assembled CAD model and a modular assembly layout. ### Required manufacturing documentation Provide: 1. Total number of printable parts. 2. Dimensions of every individual part. 3. Recommended printing orientation. 4. Recommended wall thickness and infill. 5. Assembly sequence. 6. Joint and waterproofing details. 7. A complete parts list with part names and quantities. Do not create any component larger than the printer's 270 × 270 × 270 mm build volume.
