Update: A federal judge in Seattle has issued a temporary restraining order[1] stopping the designs for 3D-printable guns from being posted online.

Cody Wilson, the founder of Defense Distributed, tweeted that he has filed lawsuits to dismiss the challenges in New Jersey, Los Angeles[2] and Washington state[3].

The publication of the files comes after a three-year legal battle between Defense Distributed and the State Department. In 2013, Wilson published designs for a single-shot pistol that could be 3D printed out of plastic and fabricated with easily accessible metal parts.

The State Department said the files were in violation of federal arms export rules and ordered Defense Distributed to take them down. Wilson sued the government on
