About this 3D model

This is an 3D adaptation of the popular 2D Matsuyama Paradox. The idea is that the cube is put together without the center cross and it just barely fits in the box. You then have to rearrange the pieces to get the cross inside and still fit in the box. This is a fun and challenging puzzle. It is a brain teaser every time you put it together. The idea was generated based off of the work of Rod Bogart.
