I am trying to create a simple nameplate model using three.js and three-bvh-csg and export it as STL for 3D printing, but no matter what I have tried the mesh always has non-manifold edges. I have this mesh working in Python using trimesh and shapely but I need to refactor it in JS. My nameplate ha…

Use the Manifold CSG library. It’s way more robust and really fast. [image] GitHub - elalish/manifold: Geometry library for topological robustness Geometry library for topological robustness
