The prompt
Create a beginner-friendly 3D mechanical CAD concept of a foldable smartphone desk stand with a dual-hinge Z-fold design. Use millimetres. The design should include a rectangular base measuring 140 × 80 × 6 mm, one supporting arm approximately 110 mm long, and a phone holder approximately 75 × 110 mm with two bottom support lips. Include two pivot joints: one between the base and supporting arm, and another between the arm and phone holder. Use approximately 5 mm diameter pivot holes. Make the parts separate solid components suitable for assembly in Siemens NX. Keep the geometry simple, with flat plates, rounded corners, cylindrical pivots and no decorative features. Show the stand in its unfolded position, and aim for a design that can fold flat. Export each component as an individual STEP file if supported. This is a preliminary concept. Identify any missing dimensions, interference problems or unclear joint connections rather than inventing unverified mechanical details.
