Dome made from the Truncated Cube with Octagrams added

The truncated (chopped off strategically) cube, which has been divided and projected onto the spherical surface. Large number of elements suggests a dome for larger sizes, approximately 20 to 35 feet diameter.

A very unique dome with Octagrams - 8 sided stars - of  which only the top one is complete.
If the long struts (orange) were 8 ft, smallest struts would be 2 ft 8 inches, and dome diameter would be 30 ft 6 inches.
