sailfish 3d model

Create a 3D printable articulated “flexi” sailfish (pez vela) model designed for FDM printing. The model must be print-in-place with a segmented flexible body (like a flexi dragon), allowing smooth movement without assembly. Include a functional lower jaw that can open and close. The jaw should use an integrated hinge or snap-fit pin system with 0.2–0.3 mm tolerance so it does not fuse when printed. The mouth must open around 25–35 degrees and include a stop to prevent overextension. The jaw must match the head shape naturally (no blocky geometry), maintaining an organic, realistic sailfish look with a long bill, dorsal sail fin, side fins, and tail. Constraints: * No supports required * Minimum thickness 2 mm * Optimized for PLA, 0.4 mm nozzle * Durable joints that move freely after printing Output a clean, manifold STL or 3MF with all moving parts functional. Do not generate a static model.
