A polyhedral shape interlocking puzzle designed and made by Junichi Yananose in 2017. The shape of the puzzle is based on a compound of two tetrahedra.
The puzzle is the smallest family members of the Reza series. The puzzle is easier compared to its two larger family members, Reza 6-8 and Reza 12-20 and it can be assembled without using the aid of rubber bands.
Juno designed the puzzle to have all twelve pieces different. He also chose the combination of pieces to make the puzzle stable when the puzzle is assembled.
It's hard to describe the size of the puzzle by length, height and width because of its unusual assembled shape. The length of sticks are 160 mm and 120 mm. Please also refer to the images below to estimate the size of the puzzle.
