I’m working on a sleek, contemporary ring and need a production-ready CAD model to bring the idea to life. I’ll share my sketches, stone sizes, and the exact finger size once we start; what I’m looking for from you is a clean, accurate 3D file that a manufacturer or 3D printer can use straight away. The finished deliverable should include: • A fully parametric CAD file (Rhino, MatrixGold, or similar) • An export in STL or STEP suitable for casting • Basic turntable or still renders so I can approve the look before sign-off Please build in allowance for one round of minor adjustments after I review the first draft. If you’ve designed modern rings before, especially with tight tolerances, I’d love to see a couple of samples when you bid.
