Hah! I actually got this file from headfi. Someone was kind enough to post their design and I had to print it.
It’s sort of hard to tell from the picture, but it’s double-layered honeycomb. Makes for a very solid structure which also looks fantastic 
I’m going to do a single layer of honeycomb and see how that turns out because it doesn’t sound as open as I’d like. I’ll play around with some designs this weekend… should be fun.
Also still waiting for my CF band + yoke kit to ship from Audeze… haven’t had an update in a good bit.
