Car Headrest Hooks - Snap-On Bag Hangers for 12-15 mm Headrest Posts, No Supports (OpenSCAD)

Snap one onto the metal post of a car headrest and hang shopping bags, a handbag or a backpack behind the seat, off the floor. The clip springs round the post, and the hook arm ends in a curl so handles can't slide off. DETAILS • The plate has four: two for 12-13 mm posts and two for 14-15 mm posts. Measure yours. • 14 mm thick, 42 mm arm. • Prints flat with no supports, layers along the hook. Bambu Studio: 55 min, 27 g for four. • Use PETG or ASA: PLA can soften in a hot car. CUSTOMIZE (OpenSCAD) Post sizes, thickness and arm length. Designed with AI assistance (OpenSCAD). Rendered images; not printed or tested in a car yet.
