The prompt
Create a 3D model of a universal car cup holder that can automatically open and close. The mechanism should be simple and suitable for 3D printing (no tiny fragile parts, wall thickness ≥ 2 mm, overhangs ≤ 45°). It must fit a standard coffee cup (diameter ~85–90 mm) and a Coca‑Cola can (diameter ~65 mm, height ~120–140 mm). Design a telescopic or adjustable inner sleeve so that both items are held securely. Include a basic latch/stop mechanism for the lid. Output as a clean mesh with no internal geometry errors, ready for slicing. Show the model in two states: fully open and fully closed.
