摘要：In a die which has a regular polyhedron form and which can be opened into acontinuous polygonal form on a plane, boundary areas (Rb) between planes (through ) onthe inner side of the regular polyhedron have inclination angles determined according to
the regular polyhedron. In addition, engaging portions () not exceeding the respectiveboundary areas (Rb) are placed on the boundary areas (Rb) of predetermined planes(through ). Such a die is formed by injecting plastic resin within a mold () according to theform of the opened die. This realizes a three-dimensional die capable of being openedonto a two-dimensional plane, which has only been fictionally conceived, and furtherprovides a manufacturing method thereof.
