Cube Puzzle Box

A 6 piece puzzle that comes from the dissection of a cube. The problem is to return the pieces to the box after the box is emptied. It looks difficult as the longest sides of the pieces correspond to the longest diagonal of the cube - also there are two types of pieces - mirror images. However it is not difficult and sorting the pieces into pairs speeds the solution. There is a nice illustration of the dissection on youtube: https://www.youtube.com/watch?v=ffnVCEAcOns OpenSCAD code is included.
