Icosa-Dodeca-DomeTM

Closely related to the Garden Dome 2 and Star Dome 1, it makes a great hemisphere dome. Simpler than the Star Dome 1 but more elements and roundness than the Garden Dome 2. Two sizes of triangles are arrayed strategically about the sphere surface.

Size reference: if longest struts (red) are 8 ft., dome diameter will be 30 ft. For efficient covering with minimal quantity of 4′ x 8′ sheets, dome diameter will be 25 ft – 6 inches. Two of the large triangles can be covered with panels made from one 4’x 8’sheet.

This 25 ft. dome was made from 2 x 4 lumber, painted white, with alternating triangle panels to give a windmill effect.  The dome was made with Quick Connector features allowing easier assembly/disassembly for a one day exhibition.

Compare with the Garden Dome 2-X1a – this might be called the Simplified Version of the Icosa-Dodeca Dome. Same symmetry but fewer parts and less roundness; shown here as a 20 ft 2 x 4 dome:
