Custom Motif Chain CAD Design

I need a skilled jewelry CAD artist to create a production-ready 3D model of a chain built around my personal motif. The piece isn’t a standard link style; it should feature a repeating custom pattern that clearly reflects the symbol I provide while still functioning as a comfortable, wearable chain.

Here’s what will make the project a success for me:
• Accurate 3D CAD file (Rhino, MatrixGold, or compatible STEP/STL) that can go straight to casting or 3-axis milling.
• Individual link geometry that interlocks smoothly and maintains consistent thickness throughout, suitable for precious metals.
• A few quick viewport or KeyShot renders so I can confirm the look before final export.

When you reply, show a chain or link project you’ve modeled before and note which software you’ll use. Once we agree on the motif details, I’d appreciate a first draft within a week and the finalized file after any tweaks.
