The prompt
The previously generated propeller does not match the reference image, even though the image was attached. Please do not generate another leaf-shaped or S-shaped blade. Instead, construct each blade using a controlled parametric planform defined by multiple spanwise cross-sections. Requirements: - Overall diameter: 300 mm - Shaft bore: 5 mm - Initially 2 identical blades, 180° apart - Nearly straight radial blade centerline - Asymmetric leading and trailing edges - Smooth, moderately wide blade profile - Rounded, broad blade tips, not pointed ends - No exaggerated sweeping or S-shaped curvature Define editable chord widths at 20%, 40%, 60%, 80% and 95% of blade span. Use smoothly interpolated leading and trailing edge curves through these cross-sections. The blade must resemble a conventional commercial multirotor propeller, not a leaf or scimitar. Keep blade count, chord distribution and root/tip pitch angles as adjustable parameters. Use millimeters and generate a closed STEP/STL solid for CAD visualization.
