I’ll share a clear reference photo of a vintage-inspired brass necklace and need a faithful 3D CAD model that mirrors every curve, link, and clasp detail. The final file must be ready for both rendering and manufacturing, with clean topology and the correct scale so a jeweller can move straight to casting. You can work in Rhino, MatrixGold, ZBrush, Blender, or any other industry-standard jewellery software—just export the usual formats (STL for printing, plus your native file). Texturing isn’t critical, but the surface needs to reflect brass thickness and weight accurately. Acceptance criteria • Geometry matches the reference photo without visible artefacts • Dimensions and wall thickness suitable for casting in brass • Files delivered: STL, high-res render, and editable source If this sounds straightforward for you, let me know your turnaround time and any past examples of vintage necklace models you’ve completed.
