18 inch half Death Star wall hanger with fitted joints

I took this Death Star model and used the front half to make a large Death Star wall hanger (roughly one and a half feet in diameter or 40 cm). It is cut into 16 pieces designed to fit on a Robo 3D R1 Plus. I added small fittings so it will line up easier when you're gluing it together. I also hollowed it out a bit and added a lip on the top to hang from 1 or two screw hooks.
