Solidworks for Marker Spaces is free on Windows only. I guess normal price for this is $6000-$8000 and then $2000 a year. Good product for those getting into 3D printing.
SOLIDWORKS for Maker Spaces
Using SOLIDWORKS for Makers, Maker Spaces and their participant users can get access to the tools required for modeling to develop their ideas in 3D, which can later be used to fabricate physical products or objects.
