I use FreeCAD for my 3D printing designs. It works great on Windows and Ubuntu (not so great on Mac), but for designing enclosures for electronics projects and printing them, it has met my needs. I think it takes longer to learn than AutoCAD's maker apps, but I know i will always have access to my designs. It will be a shame if all of this open hardware for 3D printing, and CNC routers doesn't result in a feature rich CAD application. From what I can see, AutoDesk saw the risk and has inserted themselves with "fun and easy" web based and cloud apps.
