Would like to have three parts to allow construction of a geodesic dome.

First part is the center of the five sided pentagon where the five triangular edges meet at the center. Need a inside and an outside piece with hole to allow bolts to pin the tubes together. Couple of different tube sizes would be helpful as well.

Second part is a the base corners. Four triangular pipes meet at the ground level. Inside and outside parts with holes to allow the pies to be pined with bolts.

Third part is a joint connector for the corners of the pentagon. I think having two choices, A three pipe connector where the entagone shape is flat, and a 6 pipe joint where the pentagon is built of triangular shapes. Inside and outside with holes to allow the pipes to be pinned as well.

Opinions / suggestions welcome!
