unfolded to folded shape. How to

Hi there!

I'm trying to develop a transportable structure with the origami logic. Actually I was able to do what is shown in the picture 1. 

I ask for help regarding two question.

1- is there a way to pass form the unfolded model I had now to the folded shape, as in the image down below (pict 2)? I think it needs kangaroo but I don't now where to start.

2- is there a way to retrieve the 2D develop of this 3D shape? I need it because I have to produce a cardboard model. 

Please help me, I'm in need and I don't know how to fix it.
