What is the best way to save a STL 3D model?

{{The best way to save a STL 3D model is to choose the right STL variant (binary for smaller files, ASCII for readability) and use reliable 3D software to preserve mesh integrity. Binary STL works best for 3D printing or fast sharing (smaller size), while ASCII is only needed if you plan to edit the file manually. Use tools like Blender, Fusion 360, or Meshmixer to fix common mesh issues (e.g., non-manifold edges) before exporting. For 3D printing, save as binary STL and preview the model in a slicer (like Cura) to check for missing faces or errors before finalizing.}}
