The prompt
Design a manual cardboard mechanism to lift 50 CD jewel cases, one at a time, 20 mm up and down, using a rotating handle that steps sequentially and stops after case 50. Start with a 3 case prototype, then scale to 50. Provide a labelled 3D model, side and top views, measurements, materials, and step-by-step instructions. Focus on sequential cams, cam grooves, or indexing, not a generic crank-slider.
