Origami Tower Box

One of the advantages of submitting diagrams to origami societies and conventions is, that if they are published, you receive a free copy of the publication.
That's how I got the Orison magazine Number 4 - 2012, published by the Origami Society Netherlands, where the diagram of my model Butterfly Tato was published.
It's in this magazine, that I found the instructions to make this beautiful Tower Box, designed by Winson Chan.

The Tower Box is a set of stacked boxes, where the lid of one box is connected to the base of another box. It has three different sections: bottom, middle and top. I folded three middle sections, but you can fold any number of them.

Each section of the box is folded with several pieces of paper of the same size (modular box): 5 for the bottom, 8 for each middle, and 4 for the top. I used 6" (150 mm) squares of scrapbook paper.
Besides the Orison magazine, I later found out that the instructions to fold the Tower Box are also available here.
