The prompt
A single 3D mechanical CAD part for a trumpet music lyre mount (Main Body with Paddle). Geometry details: 1. A 18mm-wide semi-cylindrical clamp arc for a 28mm diameter cylinder, wall thickness 4.5mm. 2. The top of the clamp integrates a female hinge lug: a 15mm outer diameter cylinder with a parallel 4.3mm horizontal through-hole. 3. The lower flange of the clamp extends 10mm outwards with a vertical 4.3mm bolt hole and a 7.8mm wide, 3.5mm deep hexagonal nut pocket on the side. 4. From the back of the arc, a flat paddle arm (7mm thick, 85mm total length) extends horizontally, ending in a rounded circular head. 5. The circular head contains a top-facing recessed circular pocket: exactly 33.5mm diameter and 4.0mm deep. All holes and features are strictly aligned along standard orthogonal axes. Flat bottom, watertight, clean CAD model for 3D printing.
