The prompt
Create a single solid mechanical part consisting of two integrated cylindrical shapes with parallel, offset axes. MAIN DISK: Large circular flat disk. Radius: 20 mm. Thickness: 3 mm. Its center defines the main disk axis. SMALL HOLLOW CYLINDER: Very small outer radius compared to the main disk. Very short axial length, significantly smaller than the main disk radius. Hollow, with a cylindrical through-bore. Its axis is parallel to the main disk axis and offset by 3 mm from it. It protrudes from only one side of the main disk. Its bore is designed to receive the motor mounting feature. Its outer surface should allow threading if required. The small hollow cylinder must be positioned eccentrically, not at the center of the main disk. Both cylinders must be fused into one continuous solid body. The hollow bore must remain open. Create a simple mechanical CAD model without decorative features. Exportable as STEP and STL.
