Modular Mars Base

I went back and redesigned the interior structure improving the connections of the vertical 4x4 square and circular plates, as well as drawing the panels in flush against the octagons and eliminating the small gaps in the original model.  Additionally, the stem in the greenhouse was recolored to more accurately reflect a tree trunk and branches (the cover was removed to show the change).  I also realized the small trophy figures are the perfect size for residents of the Martian base.

It was suggested that I show how this design is modular.  So I've taken the two smaller modules and moved them around to show how you can build different configurations off the main hub or add your own to the existing design.
