Lithophane shell

Max radial thickness — dark areas (mm) Min radial thickness — light areas (mm) Wall height (computed — matches image aspect)

—

wall height = arc length × (image height ÷ image width). Arc length = outer radius × arc angle (rad). Your mesh grid already keeps pixel rows/cols proportional to the photo — this locks the physical mm shape to the same aspect ratio.

Wedge arc angle (°) Outer arc radius — wedge / solid rim (mm) Wall inset from outer rim (mm)

Lithophane starts at Router − inset and thickens outward toward the rim. Use at least your max radial thickness so the wall stays over solid plastic (stable). Larger inset = more toward the middle of the wedge.

Single STL: pizza-slice wedge base plus curved lithophane whose inner wall sits inset from the outer rim (see Wall inset) so it rests on solid base, not the knife-edge. Image columns follow the arc; image rows run bottom→top along the wall. Dark areas extend farther outward radially (max thickness); bright areas stay thinner. Live 3D preview matches the downloadable STL (orbit/zoom with the mouse). Place flat on the bed: bottom of wedge at Z = 0. Tune inner radius so the apex prints cleanly.
