The prompt

Create a flat circular ring (annulus) 3D model, like a wheel-shaped chart, divided into 12 equal sectors of 30° each. Dimensions: - Outer diameter: 300 mm - Inner diameter: 220 mm (open center) - Thickness: 10 mm Sectors: - Separate the sectors with thin radial grooves, 1 mm wide and 2 mm deep. - Raise each sector's top surface 1 mm so the sectors read as separate segments. Labels: - Engrave each sector's text 1 mm deep, readable from the outside edge. - Go clockwise from the top (12 o'clock) in this order: 1. Acids 2. Bases 3. Salts 4. Oxidizing Substances 5. Reducing Agents 6. Organic Solvents 7. Polymers & Resins 8. Lubricants 9. Buffers 10. Disinfectants 11. Gases 12. Biological Chemicals Finish: 2 mm fillet on the outer edge, with a smooth flat bottom for 3D printing.
