    screwHoleRadius: 1.0,
    screwPatternRadius: 5.0,   // distance from center to screw hole centers
};

// 2. Extract parameters (destructuring – cleaner & more idiomatic)

// 3. Main cylinder (outer body)

    radius,           // radius top
    radius,           // radius bottom

// 7. Combine solid parts first (union)

// 8. Subtract all cutouts in one go

// 9. Return result + current parameters
