I was hoping for some comments on this dome design I came up with to take to Burning Man. With the high price of conduit these days, I wanted to come up with something sturdy using 1/2", but not too small and most importantly: cheap!

Here's the basic design, thanks to desertdomes.com for the original diagram:

The measurements are not exact, just working figures I've been using to help me conceptualize.

The main concern I have is whether the door will disrupt the structural integrity.

Any comments?
