The prompt
An ultra-slim, high-efficiency vertical hydrodynamic shaft cover (fairing sleeve) for an electric trolling motor, optimized for FDM 3D printing using ASA filament. Total vertical height is exactly 400mm. The design consists of two symmetrical halves that clamp together around a 28mm shaft. The internal cylindrical channel is exactly 28.5mm in diameter to account for ASA material shrinkage. The external profile is an optimized, aerodynamic teardrop shape with a maximum thickness of only 34mm at the front, tapering smoothly to a sharp trailing edge at the rear. The internal structure must be completely solid (100% infill density). Along the split line, include deeply recessed internal pockets designed to fit standard M10 hex nuts (for M6 bolts) and matching 6mm diameter bolt holes. Geometry features filleted internal corners to prevent stress concentration during ASA cooling. Clean engineering geometry, watertight 3D printable mesh."
