Love it! I don't have a 3d printer yet, but this is exactly why I want one. Have you build a full dome with these designs? I'd be curious to know how much plastic the connectors actually use. Also, how's the strength?
R. Buckminster Fuller designed a bookshelf for a geodesic dome structure. It provided down force at a few points near the top of the dome (improved structure stability) it was held in place via 6 cables and the shelf itself was a hexagonal pillar. The way it hung in the structure also made it stationary, unless it was lifted. I don't know why, but I always found this design elegant and ingenious.

This may just be me being silly, but here is a link to his patent:

I like your modification. probably would print faster less plastic. How well would the overhangs print?
Marten - in reply to c60
I have been playing a bit with, I prints well to my needs. My dome is build with 8M rods and I want I a hammock in there, so I prefer it a bit stronger. For a V1 the angle is wrong, I am trying 30 degrees now.
