How I built a tool that converts SVG files into 3D letter fabrication files (STL + DXF)

The problem Every time a client wanted dimensional letters — for a sign, an installation, a storefront — I hit the same wall. Either I had to hire a 3D modeler, or spend hours in Blender manually extruding paths, fixing normals, and setting up tolerances for the acrylic slot. Neither option was good. Hiring someone adds cost and back-and-forth. Blender works, but it's slow and overkill for something that's essentially a parametric operation on a 2D shape. So I built FacLet3D. What it does You up
