This is an scad file that will generate connectors for geodesic domes, hopefully.
My goal is to use this with tent poles, since it's fairly easy to come across a non-functional tent with lots of functional poles.
According to http://www.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.
Checkout http://www.desertdomes.com/graphics/dome/2vdiagram.gif for assembly diagram.
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.
