After realizing the potiential quality assurance issue that is quickly rising ... I'm thinking more and more about going all out steel. It is thinner and will provide a far better look due to this. Cost is far more but I think it may be worth it.

After playing around with 4 sheets of paper, 8 staples, and 6 small peices of tape to make a mock prototype, it was damn strong. way stronger than I would have imagined. They will be far more expensive but I can get them prefabbed so time spent goes way done.

I still need to get costs estimates on this however. I also just did some calculations and I think I can actually fit in 8 modules instead of the 7 by going steel since it is so thin.
