Proscribed Printables
Interesting milestone in open-source 3D printing over at Thingiverse: User crank has published a freely-downloadable magazine for the ubiquitous AR-15 rifle. As downloaded, crank’s magazine only holds five rounds, but a person with basic 3D modelling skills could modify it with little difficulty to produce a “high-capacity” magazine. I’m not sure what the current state of law on magazine size limits is, but prior to the sunset of the Federal Assault Weapons Ban (Wikipedia) in 2004, manufacture of an AR-15 magazine with a capacity of more than 10 rounds was an offense.
