Square Profile Ring Band (Robust Core)

1. CRITICAL DIMENSIONS (FINISHED VS. PRINT SCALE) These print dimensions include a mandatory +2.0% scale compensation to account for gold thermal shrinkage and manual post-cast cleanup/polishing. Internal Profile: Perfect circle. Target Finished Diameter: 16.10 mm (Standard US 5.5) REQUIRED 3D PRINT DIAMETER: 16.42 mm Band Width (Face Height): Target Finished Width: 4.50 mm REQUIRED 3D PRINT WIDTH: 4.60 mm Wall Thickness (At Thinnest Point / Center of Flats): Target Finished Thickness: 2.00 mm REQUIRED 3D PRINT THICKNESS: 2.05 mm Wall Thickness (At Thickest Point / Soft Rounded Corners): Target Finished Thickness: ~3.00 mm REQUIRED 3D PRINT THICKNESS: 3.06 mm 2. EXTERIOR GEOMETRY & FLAT SPOTS Exterior Shape: A soft, squarish profile featuring four distinct flat panels connected by smoothly filleted (rounded) corners. Orientation: The four flat sections must sit perfectly perpendicular to each other (90° orientation around the outer radius). Transition: Fillet the four outer corners generously to ensure a smooth, comfortable exterior that doesn't feel sharp to adjacent fingers. 3. SEASONAL RELIEF ENGRAVINGS (SAND-CASTING SPECS) Standard shallow engravings will fail in sand. The relief designs must be thick, bold, and geometric to allow molten gold to flow cleanly without trapping air. Engraving Depth: 1.20 mm deep into the flat face panels. Draft Angle (Crucial): All vertical walls inside the engraved icons must feature a 15° outward taper (draft angle). Designer Note: Do not use straight 90° vertical cuts. A 15° slope prevents the casting sand from sticking, tearing, or collapsing when pulling the master pattern out of the mold. Icon Styles (Keep linework thick, minimum line width of 0.8 mm): Winter Panel: A bold, geometric snowflake silhouette (utilizing a thick asterisk/cross shape with diamond tips). Spring Panel: A solid, simplified leaf sprout or two-leaf split bud silhouette. Make sure the leaves are small and the stem is long Summer Panel: A bold, solid central sun circle flanked by thick, blocky triangular rays. Autumn Panel: A high-contrast, block-style silhouette of an oak or maple leaf outline (no fine inner vein details).
