Turn any photo into a 3D print that glows in backlight. Free lithophane generator that runs in your browser — print-ready watertight STL/OBJ, live 3D preview, nothing uploaded, no sign-up.
Free, offline & super simple "CAD" / 3D design tool to rebuild models from pictures into print-ready STL files.
Image to STL converter: upload a photo or PNG and get a watertight, slice-ready STL. Image to 3D model free to start, with one-click repair and 3MF export.
Claude Agent Skill: convert a black & white image into a 3D-printable relief printing plate (STL) for a rolling press / brayer — with auto-tiling (hidden dovetail joints) for plates larger than the printer bed. Tuned for the Bambu Lab X2D.
Turn an image or heightmap into a watertight, millimetre-scaled STL you can slice without repair. Zero dependencies, runs in the browser.
