CORE 5.2 LTS: Modelling - Exercise... but maybe a bit too much :-)

Haha - I don't think it's too much.
Over engineered?   Nope.
This hallway has to withstand the astronomical forces of the granite mountain that the secret base is located under.

Maybe you need a few extra redundancies?
What if there is a Tsumami, Earth Quake, Asteroid and a Nuclear Explosion all at the same time.
I mean the chances of that happening is not 0.

Oh, that's no good; I believe that no longer qualifies as Box Modeling😉

Seriously though, that looks amazing! Fantastic work!

Dangs that looks awesome. Feels like I'm in the hangar launch bay of the Collab robot.
