No response yet? I didn't think my questions were that complicated. What I really need to know is how thin can I make my tablet holder and how narrow can I make the perimeter section and crossbeam sections. I don't know if these are the best terms, but I think the picture makes clear what I'm talking about. I am considering nylon, but since my last post, I've also been thinking about aluminum. I did several Google searches, but cannot seem to find any info as to weight-bearing strength of these materials. Perhaps I don't know the right terms since my engineering background is essentially nonexistent.
