tugboat 3d model

Design a functional RC tugboat-style ship for real-world 3D printing, not decoration. Length ~80 cm, width 28–32 cm, height 30–35 cm. Use a classic tugboat hull: rounded blunt bow, wide beam, deep displacement hull, flat reinforced keel, optimized for stability and torque, not speed. Hull wall thickness 3–4 mm, internal ribs and bulkheads, watertight design with gasket-ready seams. Raised front deck, compact central wheelhouse, and open rear working deck. Large internal volume for battery, ESC, receiver, motors, wiring, and ballast near the keel. Rear-mounted large propeller (single or twin), optional Kort nozzle, rear rudder(s). Include a rear payload bay carrying 300–700 g with a servo-controlled drop hatch/trapdoor that releases payload on RC command. Removable deck or superstructure for maintenance. Split model into printable sections with alignment pins and screw holes. Traditional industrial tugboat appearance, realistic proportions.
