So I looked at some ADA tank stands to see how they do it, and I looked at the stand I have some more and I did a redesign. I think what I have is pretty excellent right now. The whole thing would be made from 3/4" plywood (cut almost exclusively into rectanglular pieces), which is good from a monetary and simplicity perspective.
I also added a drawer because I wanted to. But I am worried that it will compromise the stands integrity. It probably won't, but if anyone has any experience with this sort of thing, let me know. Also, if you see any other weak spots, I'd love to know.
