(CNN) - A Texas man who tried to post plans for a 3D-printed gun online has been charged with sexually assaulting a child.
Cody Wilson is accused of having sex with a girl under the age of 17.
Authorities said the incident occurred in Austin, TX, on Aug. 15, and Wilson paid the girl $500.
An affidavit filed in Travis County said the girl told police she met the 30-year-old on the website SugarDaddyMeet.com.
Wilson first rose to national prominence several years ago, when he posted designs for a 3D-printed handgun online.
The government ordered the blueprints to be taken down, and Wilson sued.
A legal battle followed. Most recently, Wilson said he would sell flash drives containing the files necessary to 3D print a gun.
