The prompt
Design a parametric 3D CAD enclosure for my electronic PCB. - External dimensions: 91 × 82 mm. - Two separate solid parts: bottom housing and removable top lid. - Internal components reach approximately 40 mm above the PCB. Make the enclosure tall enough to provide 3–5 mm clearance above the tallest component. - Add internal guide rails so the PCB slides into the housing from the top, like a CD. No PCB screws. - The lid must be removable upward and secured with reusable snap-fit clips, without screws. - Create exactly one side opening for the existing USB-C connector, aligned with its actual position. No other side openings. - Initial wall thickness: 2 mm. - Make dimensions, clearances, rails and clips editable. - Design for FDM 3D printing. - Output editable solid CAD geometry, with separate base and lid, suitable for STEP export. - Do not invent PCB dimensions or USB-C coordinates. Use adjustable parameters where measurements are missing.
