I already have a clear photo reference of the ring I want and now need it translated into a precise, production-ready 3D model in Rhino. The design is modern, the band stays plain, and the setting must hold a diamond that will later be engraved. What matters most to me is accuracy: the seat, pavilion clearance, and overall proportions have to match standard diamond tolerances so the stone drops in perfectly when cast. The model should be fully water-tight, filleted where appropriate, and ready for direct export to STL or 3DM for my caster. High-quality key-shot style renders (or native Rhino render) are a plus so I can show the final look to my client before committing to metal. To make sure we are on the same page, I’ll send over the reference photo, exact finger size, and stone dimensions as soon as we start. Please keep the original layer structure intact and name them logically for shank, head, stones, and any supports—this speeds up any later revisions. Deliverables: • Rhino (.3dm) master file, clean and editable • STL ready for printing/casting • 2–3 rendered images from different angles If you have a background in jewelry CAD and have taken similar projects from sketch to bench, this should feel straightforward. I’m available for quick feedback loops and would like the first draft in three days, final files within a week.
