I built one. :o
I'm proud of my dish. I actually didn't intend for it to be this big.. it just kind of happened.
(just realised- the schematic text is a bit small to read due to flickr resizing, the full sized image is in the bshelf gallery for those interested, and until it's modded, deeplink.)
The dish actually uses a similar technique to that of the ring
segments of my Khet Nasari, although mid-way through the building
process I realized that that particular spacing couldn't form a full
ring, and so this has gaps that are a bit larger..
An 11 segment ring would have the best spacing as far as I can tell, however that's highly unstable (at least with click hinges) so I added one more segment to make 12.
