When people need this
The usual route is Sketchfab or Poly Haven, then a slicer that refuses the file. People also land here after exporting from Blender in the wrong format, or after pulling a model out of a web viewer that only offers GLB.
GLB to STL converter
GLB is what you get when you download a model from Sketchfab, an asset store or an AR viewer. A slicer cannot read it — it wants bare triangles and nothing else. This converter strips the model down to exactly that.

Check the size in your slicer before printing. glTF normally works in metres and STL in millimetres, so a model that looked right on screen can arrive a thousand times too small.
