The prompt
Create a 3D model of a bottom access lid for enclosing the spring engine inside a home plate base. Geometry: - Flat circular disk measuring 4.95 inches in diameter and 0.25 inches thick (sized to fit snug inside a 5.0-inch pocket). Feature 1 (Mounting Screw Holes): - Four countersunk screw holes (0.18-inch diameter) spaced evenly 90 degrees apart around the perimeter, positioned 0.3 inches inward from the outer edge. Design Intent: - Watertight solid body designed for 3D printing in ABS or PETG.
