Sparrowvsrevolution writes "The promise of a fully 3D-printable gun is that it can spread via the Internet and entirely circumvent gun control laws. Two days after that digital weapon's blueprint first appeared online, it seems to be fulfilling that promise. Files for the printable gun known as that 'Liberator' have been downloaded more than 100,000 times in two days, according to Defense Distributed, the group that created it. Those downloads were facilitated by Kim Dotcom's startup Mega, which Defense Distributed is using to host the Liberator's CAD files. And it's also been uploaded to the Pirate Bay, where it's one of the most popular files in the filesharing site's uncensorable 3D printing category."
