How about the hubs to make a rhombic dodecahedron ?
This would require 8 tri-pod hubs and 6 quad-pod hubs...
And the angles are fixed and therefore it should be logical to
assume, that will be capable to be made stronger than those
of variability to incidental angle.
Several advantages may be imagined as well...
Same edge length for construction throughout.
Same face shape for all faces.
Even though the same edge is used throughout,
any starting length can be used.
A modular approach may be applied. For instance,
they could be built into a structure containing four rhombic
dodecahedrons that support a fifth....
like four spheres that support a fifth ?
