Use when the user wants to 3D print, emboss or extrude a flat image.\n---\n\n# Line art to STL\n\n## Steps\n\n1. Use the image the user shared. Flat, high-contrast art works best: logos, silhouettes, outlines, text.\n2. Ask for the size and thickness if they matter, and pass `size_mm` (the longest side) and `thickness_mm`.\n3. Call `image_to_stl` with the image (free). The card offers the STL download.\n\n## Tips\n\n- For a real 3D object from a photo, use the photo-to-3d skill instead.\n- Raise `min_feature_mm` if thin details would be too fragile to print.\n"
