High-Precision Mechanical Part STL

I need a seasoned 3D CAD designer to convert my annotated sketches into a manufacturing-ready model of a small mechanical component. The file will be used directly for prototype production, so tight tolerances (±0.03 mm) and clean, watertight geometry are critical...
