This is my model I made in FreeCAD. I made this model based on the new telescope "ELT" that is going to be built and the model logo is the site that made paper model of ELT. You can download and then print those files on their site.

If you don't know, ELT is going to be the worlds largest telescope. The giant ELT dome will house the telescope and its interior structure, providing protection from the extreme environment of Chile’s Atacama Desert. The main structure of the telescope will hold its five mirrors and optics, including the enormous 39-metre primary mirror. (pasted from " [https://elt.eso.org/telescope/"](https://elt.eso.org/telescope/"))           ELT- Extremely Large Telescope
