Cyberpunk Ring Design & 3D CAD

Create some cyber-punk, futuristic ring concepts, each sketched by hand, and very slightly inspired by fantasy movie aesthetics. Some sketches have been done but can be refined or expanded on. Designs then need to be translated into fully detailed CAD models. My key goal is to hand a manufacturer a complete digital package that captures every contour and surface treatment exactly as envisioned.

Textures
The silver must display distinctly different finishes: Matte, Polished, Molten and burnished areas should read clearly in both the renders and the technical files, helping the caster understand where to high-shine, where to leave a soft glow, and where to keep a raw, almost liquid look.

Scope of work
• Build precise 3D geometry for every ring, following the supplied sketches without simplifying the cyber-punk styling or structural details.
• Apply and show the four surface treatments above while keeping the overall metal volume realistic for sterling silver.
• Produce studio-quality renders from multiple angles that can double as marketing visuals.
• Generate manufacturer-ready files: STL (for printing), plus dimensioned technical drawings that include finger size, overall height, wall thickness and any under-gallery work.
• Provide source files (e.g., Rhino, MatrixGold, ZBrush or equivalent) so later tweaks remain possible.

Acceptance criteria
The job is complete when the STL passes standard watertight checks, textures are clearly visible in the renders, and measurements match the sketches within ±0.1 mm.

With those deliverables in place the designs can go straight to the caster without further adjustment.
