Minimalist Pendant Necklace CAD Modeling

I am developing a clean, minimalist pendant necklace collection and need precise 3D CAD files that are ready for both renderings and manufacturing. The focus is on elegant geometry with no ornate flourishes—think subtle curves, balanced proportions, and smooth surfaces that translate well to precious-metal casting.

You’ll receive my hand-sketches and basic dimensions; your task is to translate them into a fully detailed digital model, refine tolerances for typical fine-jewellery production, and supply high-resolution renders so I can review every angle before we move to prototyping. I’m comfortable with you working in Rhino, MatrixGold, or another professional jewellery CAD package as long as the final files arrive in STL for printing and 3DM or STEP for any further edits.

Deliverables:
• Finished 3D CAD model of the pendant and integrated chain loop
• STL file optimized for 0.03 mm print accuracy
• Native design file (3DM or comparable) with clean, editable history
• Two beauty renders (front and perspective) on a neutral background

I’ll provide prompt feedback, so good communication and quick iteration turnarounds will be appreciated. Let me know your preferred software and any similar minimalist pieces you’ve modelled, and we can start right away.
