3DGEN

3DGEN is a set of parametric generators that run entirely in your browser. Upload an STL and get a printable two-part mold, silicone mold box or plaster casting mold, or start from text, an outline or a photo and make cookie cutters, nameplates, keychains, stamps, lithophanes, pet bowls and more. Adjust a few sliders and export a print-ready STL or 3MF. Built for makers who don't want to learn CAD: candle and soap makers, resin casters, clay artists and anyone with a 3D printer. No signup to try; files never leave your device. Freemium: free plan for personal use, Pro for commercial use.
