About Lithophane Generator

Drop a photo and get a watertight STL in three shapes: a flat backlit panel with an optional frame border, a curved arc segment, or a closed cylinder lampshade. Darker areas print thicker so the image appears when lit from behind — invert and auto-contrast options included.

Tune the thickness range and detail level, then check the result in the live 3D preview before downloading the binary STL with volume and filament estimates. The mesh is generated entirely in your browser — photos are never uploaded.
