The prompt
Using the uploaded reference image, create a precise parametric 3D CAD model of the Waveshare L-shaped Permanent Magnet DC Gear Motor shown. Use the uploaded image as the PRIMARY reference for shape, proportions, orientation, hole locations, shaft position, and assembly geometry. Use the dimensions visible in the image exactly where provided. Key dimensions: - Gearbox front face: 38.0 × 64.4 mm - Corner radius: R12.5 mm - 4 mounting holes: M3 × 0.5 - Hole spacing: 26.5 mm horizontal × 50.0 mm vertical - Output shaft: Ø6.0 mm - Shaft protrusion: 12.0 mm - Shaft-end flat: 5.4 mm - Gearbox side dimension: 23.5 ±0.5 mm - Front plate thickness: 3.0 mm - Motor diameter: 33.0 mm - Motor body length: 22.5 mm - Rear connector depth: approximately 8 mm Reproduce the actual right-angle/L-shaped motor and gearbox arrangement shown in the uploaded image. The motor axis must be perpendicular to the output shaft axis. Create clean solid mechanical CAD geometry with the four mounting holes, output bearing/boss, shaft, cylindrical motor and rear connector. Keep the major dimensions parametric/editable. Do not invent dimensions where the image provides them. Do not confuse the 5.4 mm shaft-end flat dimension with the Ø6 mm shaft diameter. Do not add unnecessary wires, logos or decorative details.
