3d printed mechanical mount

"A white 3D-printed plastic mechanical mount, engineering CAD-render style. A flat rectangular base plate on a workbench. A vertical column with a long slot cut into it rises from the base. A rectangular carriage block slides along this column, held in place by a black thumbscrew through the slot. Attached to the carriage by a single metal pivot pin is a small curved cradle holding a cylindrical stepper motor with a thin metal rod extending out one end. A curved arc-shaped slot with a second black thumbscrew locks the cradle's tilt angle. No screens, no buttons, no electronic displays anywhere — just plain white plastic parts, a metal pivot pin, two black thumbscrews, and one gray cylindrical motor. Soft even studio lighting, light gray background, minimalist product photography, three-quarter angle view."
