i love this concept ; i have recently wanted to buy a 3D printer, perhaps i shall follow more about this story .
Ive wanted to use the 3D printer for various tasks and fabric sounds like it would be a tough job - although very interesting at the same time ; ive recently seen a jacket in development with heating pads in different sections for those crazy cold winter days .
This is what comes to mind when i read this and im sure there are many more ideas floating around in my head .
Perhaps a little pocket where you can use a cell phone through a window - even during rainy weather ?

Just thinking out loud - so to speak lol !
Very interested in watching this grow !
