Though 3D-printing giant MakerBot has long had a rule against uploading any design that “promotes illegal activities or contributes to the creation of weapons” to its Thingiverse file-sharing site, it was only this week that it began enforcing the ban, pulling down several gun-related blueprints.

Now, 3D-printed gun manufacturer Defense Distributed–which ANIMAL profiled last month–has retaliated, creating a weapons-centric answer to Thingiverse called DEFCAD and uploading many of the designs that MakerBot pulled down. There are currently 11 designs available–including the Beretta 92FS/M9 frame above and two AR-15 components–with plans for seven more.
