The Right to Print Weapons is the Right to Be Free?

The federal government is trying to prevent CAD files for printable weapons from being displayed online. As Glenn Reynolds notes, they (the Clinton administration) tried to do this with cyptography.

Will they go SOPA on 3D printers by trying to cripple them and/or prevent the price from dropping?

My new sig line may be, "The right to print weapons is the right to be free", with apologies to A. E. van Vogt.
