The prompt
"Generate a 1:1 ratio straight bevel gear (miter gear). The maximum outer diameter must be exactly 20 mm. Include a center bore hole with a diameter of exactly 4.2 mm for the coupling. Use a standard 20-degree pressure angle and an involute tooth profile to ensure smooth rotation. Optimize the mesh topology to be fully manifold and solid for FDM 3D printing. Please provide the final output as an STL file."
