2V Geodesic Dome Hubs

These are hubs for a 2v Geodesic Dome. I used drinking straws (dia 5.5mm) to form the struts.
Angles are accurate to 0.1deg
For a hemispherical dome you will need
* 6 of 5-point hubs
* 10 of 6-point hubs
* 5 LHS 4-Point hubs
* 5 RHS 4-point hubs
* 35 long struts (e.g. full length straws)
* 30 short struts (88.4% of long struts)

to scale to other diameter straws / sticks / pipes, divide by 5.5mm and multiply by your diameter.

At smaller scales you don't need supports.
