Maybe we should start a section “Design” in the focusfusion.org-Wiki. Those things may be easier to talk about, when everyone can improve a design iteratively instead of working serially in a forum.
An example of open-source design is the RepRap project: http://www.reprap.org/wiki/Main_Page
And when it works, maybe also the Open Source Car project: http://www.theoscarproject.org/
By the way: The focusfusion.org-Wiki isn’t prominently linked, just from a single article, which I am too lazy to hunt down now. It should be in the headline, next to the forum-link.
