Solvespace is a FLOSS light weight 3D CAD alternative. Although it lacks the advanced features of Solidworks works really great for most of my 3d designs.

Thanks for the tip.

Another good use for VPN is to counter dynamic pricing. My wife visited a website some time ago to request the price for a ticket. When she visited the website a second time the price had increased considerably. However when visiting the price with VPN it was the original price again. It saved her a lot of money.
