Abstract: A unitary hub includes a central body and two or more tubular cylindrical prongs that can be used in conjunction with two or more struts to construct a dome or a sphere, such as a geodesic dome. The prongs have a first segment and a second segment that are disposed at an angle. The first segment has a first inner diameter and the second segment has a second inner diameter thereby creating a recess for the struts to be positioned easily and accurately within the prongs. The central body is formed from joining the two or more prongs disposed around an axial axis through a center of the central body. The central body has a top and bottom side with a spherically concaved section having a curvature. The struts may be tubular and cylindrical and can be inserted into the prongs or over the prongs.
