I see lots of open source build project out in the internet. Well maybe not a lot but for now I found two. The one we are building here. The awesome food computer.
Some of the files are in some sort of format that requires a CAD program to open and view.
Does anyone of you know of a CAD program that would be for free?
PS. The other project that I have in my toDo after this is a plastic thing http://preciousplastic.com/
