duck leg ring 3d model

Reconstruct the exact 3D geometry of the flexible duck leg ring visible in the reference photos. This is a small functional 3D-printable TPU ring, NOT a decorative object. The object consists of: 1. A circular ring at the top. 2. Two thin flexible arms extending from the bottom of the ring. 3. The ring has an opening between the two arms. CRITICAL DIMENSIONS: - Ring inner diameter: 7.5 mm - Ring outer diameter: approximately 13 mm - Ring wall thickness: approximately 2.75 mm - Arm width: approximately 4 mm - Arm length: approximately 30 mm - Overall flat mounting piece shown in the other reference images: approximately 39 mm long × 16 mm wide × 1.8 mm thick - Two holes in the flat piece: approximately 4 mm diameter - Hole center-to-center distance: approximately 10 mm GEOMETRY: - Accurately reproduce the circular ring profile. - Smooth transition from the ring into the two arms. - Two arms should be slightly curved and progressively separated. - Rounded arm ends. - Thin flexible
