About this 3D model

I saw this link(http://www.kagenschaefer.com/Book2.html) a while ago and I wanted to make it but I didn't see any images on how it worked or how to make it. I reversed engineered it and it works! unfortunately the version that I made isnt able to fit on a regular pdf so you can't just print it out, but I have an adobe illustrator file that you could use to laser cut wood or any material that you chose. It basically done but you might have to change it to fit your needs
