The prompt
Create a hollow cylindrical furnace lid (inverted cup) in millimeters: 1. Outer body: a vertical cylinder, diameter 1666, height 833. 2. Inner cavity: subtract a concentric cylinder, diameter 966, depth 483, open at the bottom face. This leaves a 350 top plate thickness and a 350 side wall thickness. 3. Through the top plate, cut these vertical ports (full 350 depth): - Port 1 (charging car access): circular hole diameter 450, centered 380 from the central axis. [ASSUMED] - Gas off-take: circular hole diameter 500, centered 520 from the axis, 90 degrees from Port 1. [ASSUMED] 4. Port 2 (lance + feeder): cut a cylindrical hole diameter 300, tilted 45 degrees from vertical, aiming toward the bath center, its center on the top plate 320 from the axis, opposite to Port 1. [ASSUMED] 5. Bottom perimeter flange: add a flat ring 60 thick extending 80 outward from the outer diameter, on the bottom face, for bolting to the bell. [ASSUMED]
