A kit and structures that may be assembled using components of the kit are disclosed. The kit includes structural nodes and structural connections adapted for connecting the structural nodes. Each structural node has a polygonal openings from a central cavity to the outside of the node. Each of the structural connections has an elongated body having two ends from which stubs having a polygonal cross section extend. The stubs include at least one outward dimple positioned so that it resides within the central cavity of a structural nodes when the stub is inserted through one of the polygonal openings with the end of the elongated body abutting the structural node.
