There is not yet a complete render or GLB file for the upright.
The upright instructions are currently based on photographs, I am working to move that to renders. Some progress is in a merge request in the repository !342. In the end that will give us a build of the entire microscope that we can export as a GLB model.
We have not actually put a photograph of the complete microscope in the instructions. There is this one: Upright microscope prototype .
