I'll have to look into the forwarding mail box thing. Didn't find it at Alibaba, did find a company here in the US that looks like they make it, but it looks like they might be out of business. I can't actually figure out how makes it, HaGa China, SMOZK China, Bantree foundries US or D. all of the above. I did find enough specs on it that it wouldn't take me much work to get it ready to have produced, but unfortunately shapeways doesn't do aluminum, the metals they do offer are way more then cost prohibitive.
Maaan I got it all figured out for an awesome DNA30 box.
