Detailed 3D Jewelry Models

I am preparing a new collection that spans engagement and wedding rings, pendants, earrings, and bracelets, and I need each piece translated into precise 3D CAD models ready for direct printing and casting. Every file must already account for proper metal thickness, accurate sizing, and production tolerances so that my caster can move straight to wax without revisions.

For each design I will provide 2-D sketches, stone lists, and any reference images you need. You will translate them into clean, watertight CAD files that include:
• Correct stone settings and exact gem dimensions
• Any requested engraving, names, or surface patterns modeled in full relief
• Final wall thicknesses and allowances suited to the specified metal

I need designs ready in 24 hours as per the order.

Preferred file formats are STL for print, plus the native format you use (Rhino 3dm, MatrixGold, JewelCAD, or similar) so I can make future edits in-house.

Deliverables for every individual piece:
1. Production-ready STL file
2. Native, editable CAD file
3. A quick viewport render or screenshot showing key dimensions and stone layout

I turn prototypes around quickly, so reliable communication and the ability to hit agreed deadlines are essential. If you have a portfolio that demonstrates similar work—especially pieces that have already been cast—please share it when you bid.
