About this 3D model

When your astronauts get to their destination what do they find? This should be a perfect size to put most of your monsters inside of. I wanted to specifically create something not functional, and just for fun. The original idea was to make it an overly complex planter. Now I may sculpt something out of clay to go inside. nothing moves, though that could be done. Everything is very modular, so components could be swapped out, reused etc. I also included the openscad file with all the parts. I recommend lowering the sphere resolution for modeling then increasing it again for final render.
