phone stand 3d model

Design an original 3D printable minimalist desk accessory that combines a phone stand and charging cable holder. The object should have a smooth rounded rectangular pebble shape, a flat stable base, one angled phone slot across the top, three separate cable channels at the front edge, and a recessed circular pocket underneath for a small magnet. It must be a single-piece FDM printable model, no supports needed, with 3 mm rounded edges, thick walls, clean geometry, and a modern premium look suitable for selling as a physical 3D printed product.
