image-to-relief-stl

Generate a watertight, printable STL from an input image by mapping colors (or grayscale) to heights.

This is an orchestrator-friendly workflow:

• Use nano-banana-pro (or any image model) to generate a flat-color image.
• Run this skill to convert it into a bas-relief model.

Practical constraints (to make it work well)

Ask the image model for:

• exactly N solid colors (no gradients)
• no shadows / no antialiasing
• bold shapes with clear edges

That makes segmentation reliable.
