Pepakura Designer allows you to easily create paper-craft models from 3D data you create from your favorite 3D software ( http://www.tamasoft.co.jp/pepakura-en/download/designer.html ) . Download and install .By unfolding this 3D model , you can print the different pieces which can be joined to form the 3D model . Dont forget to use edge id .
We used a 3D file of the Nautilus shell and scaled it . Here comes the question of size of the shell . It was interesting to find that a natural nautilus shell has a golden ratio inbuilt . so i used the Fibonacci numbers to calculate an apt scale . The scaled 3D file has been attached.
When it came to fabrication of shell 2 methods came into our mind. One method is by taking a 3d printout of the shell and another method is by making a 3d model from paper introduced to me by my teammate Nadir Najumal Hussain( http://www.quora.com/Iron-Man-Marvel-Comics-character/Has-anyone-ever-built-a-suit-comparable-to-Iron-Mans ) .
