The prompt
Create a parametric 3D-printable enclosure for a DIY smartphone projector. Use a rectangular shoebox-style body with a removable top lid and flat base. At the front, create a centered removable mount for a **75 mm diameter double-convex lens**. The lens mount must hold the lens perpendicular to the optical axis, with slight clearance and a retaining lip. Do not glue the lens. Inside, create an adjustable smartphone cradle for phones **65–85 mm wide**. The phone cradle must slide **20–50 mm along the optical axis** for focus and lock in position. Include adjustable side supports and a bottom support without pressing phone buttons. The phone and lens centers must align. The phone may be mounted upside down. Add small ventilation openings away from the optical path and minimize unnecessary light leakage. Design for **PLA/PETG FDM printing**, with simple geometry, practical wall thickness, minimal supports, and simple screw/slide/snap assembly. Make these parameters editable: lens diameter, lens clearance, enclosure dimensions, phone width, wall thickness, and focus travel. Prioritize optical alignment, adjustable focus, secure lens mounting, phone stability, and printability over appearance. Generate the editable CAD model and separate printable components if necessary.
