wooden manta ray 3d model

Create a detailed 3D model of a mechanical wooden automaton in the shape of a manta ray, designed for laser cutting or 3D printing in separate parts. The automaton must show a realistic manta ray body with two large wings (fins) divided into three articulated sections each, connected by flexible joints or hinges so that they can move in a wave-like motion. The main body should be one solid central piece that moves up and down as part of the mechanism. The base should include a manual crank system with gears, a vertical shaft, and linkages (bielas) that transfer the motion to the manta ray body. The structure should be mechanically functional, with all parts separable for assembly (body, fins, hinges, rods, gears, and base). The final model must look as if it were made of wood, with smooth rounded shapes for the manta ray and simple geometric forms for the mechanical parts below. Include the following elements: Main wooden base (box) with visible gears and crank. Vertical rod connecting the mechanism to
