Building system

A construction set comprising:

• a plurality of struts, each strut of the plurality of struts having one or more deformable openings;
• a set of hubs, each hub of the set of hubs including one or more strut coupler prongs, each of the one or more strut coupler prongs include a proximal end and a distal end, a thickness, a front face, a back face and sides, and between each proximal end of each of the one or more strut coupler prongs is a hub border and the proximal end of each of the one or more tapered strut coupler prongs is adapted to expandably deform an opening of a connected strut forming a friction fit wherein corners of the one or more strut coupler prongs are adapted to press into internal surfaces of a connected strut;
• a first subset of the set of hubs include a centrally disposed aperture surrounded by the one or more strut coupler prongs;
• a second subset of the set of hubs include a rectangular centrally disposed slot that includes a first closed end and a second end that is open at the hub border and the rectangular centrally disposed slot is configured to receive portions of a hub from the set of hubs;
• the strut coupler prongs are tapered in a direction away from the rectangular centrally disposed slot and the centrally disposed aperture, and the front face and back face of the strut coupler prongs are substantially planar, and at least some of the strut coupler prongs include an aperture at the distal end.
