I’m developing a sleek, modern necklace built around clean geometric patterns and I need a jewelry-focused CAD specialist to turn my sketches into a production-ready 3D model. The finished file must be suitable for direct metal printing—10kt White Gold or silver are the likely candidates—so wall thicknesses, tolerances and bail geometry will have to meet current DMLS or lost-wax casting guidelines. Once the digital model is approved, I’d like you (if possible) to manage or coordinate a single metal 3D-printed prototype so I can verify weight, finish and comfort in hand. If you can’t print in-house, pointing me toward a reliable service bureau is fine. Deliverables • Editable CAD source file (STEP or 3DM) • Print-ready STL scaled to final dimensions • Two to three high-quality renders for visual confirmation • Optional: one metal prototype shipped to me Acceptance criteria • Geometric pattern is crisp, fully manifold and free of undercuts that hinder polishing • All walls ≥0.8 mm, with chain loop stress-tested in the model • Final weight target ±10 % of 20 g • Prototype matches CAD within ±0.1 mm on critical joins Timing is flexible but I’d like first visuals within a week. Let me know your preferred software and prior jewelry samples so we can start shaping this piece together.
