A while back, I posted about Defense Distributed and their goal of designing a totally 3d printed gun. Their idea reminded me of the old WWII Liberator pistol that was mass produced in secret and dropped to the French resistance fighters. I like the fact that they made the same correlation and named their design after it. Save for a nail as the firing pin, it seems they have finally done it. Check out the video of it firing here.
It seems that it even uses a printed plastic spring to drive the firing pin, very nice. I suppose the .gov could ban nails now….. Suck it Gun Control! Check them out for a free download at DefenseDistributed.com
