Abstract: A toy model building set that includes pluralities of generally circular daisy elements, wedge elements, and straight and curved rod elements. The rod elements may be equipped on their ends with various types of connectors, and the rods may be either curved, angled, or straight. The daisy elements can be joined to each other in at least four distinct ways, and can be used as connectors for different elements in a variety of ways. A large plurality of the daisies can be connected together to form a generally planar element. A through hole in the central hub allows the daisy element to receive rod elements in addition to other daisy elements. The wedge elements are pie-shaped elements including two adjoining straight sides and a third curved side. One of the straight sides is equipped with a ball connector, and the other straight side is equipped with a compatible socket connector. Using these connectors, multiple wedge elements can be joined to form circular components such as wheels.
