[Effect of the invention]

 The three-dimensional assembly puzzle of the present invention assembles and disassembles five types of regular polyhedrons by inserting three types of pillar-shaped, same-shaped pieces into each regular polyhedron, and assembles the original brain as a braided puzzle. You can enjoy the fun. By completing a regular polyhedron using the same number of pieces and the same number of sides that make up the regular polyhedron, it can be used as a learning material for learning the three-dimensional geometric features of the regular polyhedron. By using a three-dimensional piece instead of an abstract side and assembling a polyhedron as a three-dimensional spatial solid, you can enjoy modeling as an object that composes the space. The size of the piece can be changed, and it can be applied to shades of lighting fixtures and huts. It can be manufactured at low cost with easily available materials.
