Hi,
Fab design! Hope you don't mind but I wrote about it in a blog.
took a while to print 26 connectors (20 hexagonal, 6 pentagonal) but it works! details + process here: http://fabricating.tumblr.com/...
My first test was 30mmX30mmX15mm with 3 holes it had enough mass there but when I upped it to 5 holes it split rather easily. The design shown is 40mmX40mmX20mm, which should have enough meat left that it won't split. I'm still not sure if I have the angles right to do a proper Tessellated Icosahedron aka the bucky ball. I've got to print out 1 of the 5 and 5 of the 6 to check I think.
Anyway all the settings to tweak are in the scad file mildly documented.

According to desertdomes.com a 2v dome has 16 degrees on the pentagon (B struts) and 18degrees on 4 of the hexagons 6 with 16 degrees on two opposite ones.

I've made a thru hole so you can bolt it with some 3mm bolt and big washers, I was having problems with it splitting where all the poles lineup.
I also centered it.

This is cool!
I thought about a tent too but a geodesic dome is one level better. ;)
Do you think it could be improved to use less material? It looks that way.
