boeing 747 3d model

Create a fully closed, manufacturing‑ready 3D model of a Boeing 747 for SLA printing. Global requirements (critical): • Single continuous watertight manifold. No separate parts, no zero‑thickness faces, no non‑manifold edges, no self‑intersections. • All geometry must be printable in single‑material SLA; do not rely on thin decals or separate shells. • Outer shell is part of the aircraft’s form (not an internal offset only). Keep thickness consistent. Overall look & scale: • Realistic Boeing 747 proportions: fuselage, cockpit nose, wings with proper sweep/dihedral, vertical & horizontal stabilizers, four engine nacelles, landing‑gear bay locations. • Target overall fuselage length ≈ <set length, e.g., 300 mm>. Maintain true proportions. • Export as watertight OBJ/GLB with UVs. Surface style & textures (entire aircraft = PCB theme): • Apply a full‑body PCB motif over the entire aircraft (fuselage, wings, tail, nacelles): green solder‑mask look with white silkscreen lines and occasional copper‑trace pattern
