I can get it to export properly if I remove the pointless "Shape -> Detail32 -> Armature" structure you have in the scene.
After a bit of debugging, I've pushed a new version that can export it even if that structure is there. The real issue was that your meshes were being put in LOD "detail32" and you had a node named "Detail32", and that the DTS name table is normally case-insensitive (but Python's key lookup is not). In a nutshell, it works now (and you don't need to change anything if you update the plugin).
For future reference, your model is so simple that you can just have the plain "lense", "nation" and "vape" meshes. You don't need any of the other objects here ("Empty", "Shape", "Detail32", "Armature", "bone").
