I used FreeCad a few months ago for the early prototype you can see in the video at www.flair.zone.
It doesn't support assemblies yet (although its on a branch!) so I just designed a linkage system extremely carefully and swiss cheesed some parts to avoid dealing with dimensions as much as i could. I used to use Inventor but Fusion 360 is nice - and its free for startups.
As soon as Freecad supports assemblies I will probably switch back. I hate booting into OSX for Cad work and back home to linux for coding.
Another vote for Fusion 360, especially on the Mac. I settled on that for 3D printing and hopefully soon desktop CNC modeling. It seems to be the only affordable yet not dumbed-down packages for OS X.
