Detailed Silver Ring CAD Design

I already have clear digital sketches of my silver ring idea (PDF/JPEG) and now need them converted into a production-ready CAD file that captures every texture and contour I’ve drawn. The model must be accurate enough for direct 3D printing or milling, so precise dimensions, correct finger size, and clean geometry are essential.

You’re free to use the jewellery platform you know best—Rhino, MatrixGold, ZBrush, Fusion 360, SolidWorks—as long as the final output is watertight and suitable for casting in sterling silver.

Deliverables
• Editable CAD file (e.g., .3dm, .3dmx, .f3d or similar)
• Manufacture-ready export (.stl and .step)
• High-resolution renders that show the textures clearly

Acceptance criteria
• Form and textures match my sketches 1:1
• Ring size within ±0.05 mm of spec
• File passes standard printability checks (no non-manifolds, reversed normals, or intersecting shells)

Once we’re aligned on the first draft I’ll give rapid feedback, so quick turnaround iterations are appreciated. Looking forward to seeing my concept come to life in CAD.
