bicycle saddle 3d model

Create a highly detailed, engineering-accurate 3D model of a bicycle saddle-mounted hydration support inspired by the EZ Hydro Gain. The model must be parametric, dimensionally precise, and suitable for 3D printing (FDM and SLS). GLOBAL DIMENSIONS: - Total length: 220 mm - Maximum width: 90 mm - Target weight: ~150 g (optimize geometry for lightweight structure) STRUCTURE: The part consists of three integrated sections: 1) SADDLE RAIL CLAMP (FRONT SECTION) - Designed to attach to standard bicycle saddle rails - Rail diameter: 7 mm (round) with tolerance +0.2 mm - Distance between rails: 44 mm (center-to-center) - Include adaptive clamping geometry: - Semi-cylindrical grooves for rails - Clamp thickness: 6–8 mm - Bolt holes for M5 screws (x2 or x4 depending on design) - Include reinforcement ribs for load distribution 2) MAIN BODY (AERODYNAMIC FIN) - Length: ~180–200 mm - Thickness: 5–8 mm - Shape: aerodynamic airfoil-like profile (teardrop cross-section) - Include internal l
