Nice one...
...tough to make though...
Those dots on the rim of the first 'circle', are they copper posts?
Just wondering, this is something that screams for 4 outlets or some kind of equiliser like g_f or morphling's...
I'm sure you calculated everything, and I'm not suspecting that this block would perform well, but this would be a really time consuming piece to machine...
What's the base thickness calculated for this beauty?
PS: you could rename it to NOVA...
