I wonder if even very simple DAE files can be converted to glTF (and GLB) files; perhaps the tools, '''glTF API''' or '''COLLADA2GLTF''' will work.  If so, then we can kill two birds with one stone; i.e., simply build DAE files, then they should be straightforwardly ported to Oculus headgear or a 3D printer.
