This beautiful model to cut out and glue together is the result of arranging five interpenetrating cubes in a highly symmetrical way.

Each cube is printed in its own colour and so it is easy to see that exactly two cubes meet at every vertex and that there are twelve surfaces defining each face of each cube.

There is a strong internal frame and multiple divisions in the golden ratio to discover.

The book contains everything you need to make the model, excepting cutting and glueing materials. With a little patience a wonderful model emerges!
