For those who worry that even 24 hours without the ability to download 3D-printed gun blueprints is too much, fret no more: The Pirate Bay is on the case.

On Thursday, the U.S. State Department successfully demanded the removal of a set of 3D-printed firearm files from Defcad, a file-sharing site run by Defense Distributed, the group at the center of the 3D-printed gun controversy.

The founder of Defense Distributed, Cody Wilson, told CNET on Thursday that he had been expecting the State Department's action, though he felt that the International Traffic in Arms Regulations permitted Defcad to host the files under exemptions for nonprofits and for dissemination into the public domain.

Still, Defcad removed the files at the State Department's request. And now, less than a day later, the peer-to-peer Pirate Bay network appears to be offering several versions of the files required to print the Liberator, which may be the world's first functional, fully 3D-printed gun. Indeed, some of the files were uploaded prior to the State Department's demand.

The federal action followed the recent introduction of a bill in the California state senate by Democrat Leland Yee that would ban 3D-printed guns, as well as a bill introduced last year by U.S. Rep. Steve Israel (D-N.Y.) that would further restrict the weapons.

But while pressure to restrict the weapons is ramping up across different arms of government, some feel that concerns about 3D-printed guns are overblown. In theory, they present a serious danger to society given that they can be hard to detect and can, in theory, be made by anyone. However, such firearms can only be created on high-end printers and have yet to be shown to be reliable or sturdy enough to last.
