The prompt
Create a compact 3D-printable motorized gearbox. Use a small DC motor mounted below the gearbox. The motor input axis and the output shaft axis must be at 90 degrees to each other. Place the output shaft in the center of a compact round gearbox housing. The gearbox should reduce speed and increase torque. Use a clean, simple industrial design. Exact dimensions and mechanical details are not important yet. Focus on the overall mechanical concept and arrangement.
