ABSTRACT:
A three-dimensional model structure is assembled by interconnecting a plurality of puzzle pieces. Each puzzle piece has at least three outer side edges and at least one joint having a substantially U-shaped mortise defined by a first leg and a second leg. The U-shaped mortise has first and second inner side edges extending from a bottom edge to define an opening. A first corner is defined between the first inner side edge and the bottom edge. The first leg is defined by the first inner side edge and a first outer side edge. A protrusion may be provided along the first outer side edge at a location substantially opposite the bottom edge of the joint, or a bump may be provided at the first corner, to reinforce the first leg. In addition, the top corners connecting a second outer edge and the inner side edges may be curved or chamfered to widen the opening of the U-shaped mortise.
