3D file tools — STL/OBJ preview and mesh stats

Inspect 3D print meshes — triangle count, bounding box and WebGL preview.

Sending bad meshes to slicers wastes filament and time. Tentaco 3D hub previews STL/OBJ and reports stats before PrusaSlicer or Cura — lightweight check without opening Blender.

Decimate heavy meshes in a desktop tool then re-verify here.
