The prompt
Create a parametric 3D multi-part assembly of a retractable car cup holder designed to fit the right-side center air vent slot of a VW Golf MK2. Generate the model as a SolidWorks-compatible STEP file. The assembly consists of 4 parts: 1. Outer Housing (Sleeve): A hollow rectangular box with outer dimensions of 85.0mm width, 45.0mm height, and 80.0mm depth. Wall thickness is 2.0mm. The front face of this housing must be angled at 15 degrees horizontally to match the curved dashboard, but the inner walls must remain perfectly straight (0 degrees) to act as parallel sliding rails. The rear face is completely open to allow airflow. 2. Sliding Tray (Drawer): A block measuring 79.5mm width, 39.5mm height, and 75.0mm depth that slides inside the housing. Cut a circular through-hole with a diameter of 68.0mm in the center to hold a standard beverage can. Hollow out unnecessary mass leaving a 2.5mm structural thickness. Add side rails that mate with the inner walls of the housing. Add a mechanical stop at the back to prevent pulling the tray completely out. 3. Front Vent Cover: A cosmetic plate measuring 85.0mm width x 45.0mm height x 3.0mm thickness. Design 4 horizontal louvers (slats) on the front face to mimic a classic car air conditioning vent. This cover attaches securely to the front of the Sliding Tray. 4. Bottom Support: A U-shaped bracket that drops down exactly 70.0mm below the sliding tray to support the bottom of the can when extended. Ensure a 0.5mm clearance tolerance between all moving parts for manual push/pull mechanism.
