Something I was thinking of after seeing so many great cardboard designs on here.Why not a Cardboard structure scanner designed in the style of a fold able tab design, like those cardboard storage boxes found in the stationary store.
Thinking about it. A light flat packable scanner that doesn't cost much , recyclable ,low cost , easy to construct and perfect for the third world. Making from flat black colour cardboard would save painting
I have seen dedicated Cardboard design software like http://www.packmage.com/
but maybe there is add-on's for more popular CAD programs. Design could be mostly virtual
I'm not so good at putting across my ideas , so hopefully people understand me
