PHOTO TO STL
Requires Python 3, Pillow, NumPy.
Install: python -m pip install Pillow numpy
Run: python photo_to_stl.py input.jpg output.stl
Input aspect ratio 4:3. Output 100x75 mm, thickness 0.8-3 mm, frame 2 mm.
STL has no units: interpret coordinates as millimetres.
Review dimensions, thin areas, orientation and layers in your slicer.
Example mesh validated as closed with consistent winding; not physically printed and not tested in a slicer.
