The Yoshee Six Shooter is an all-new 3D printed semi-automatic gun design, created by a college student named Chris and inspired by Cody Wilson's Liberator 3D printed gun. Chris used Tinkercad to design the unique piece, incorporating some ideas from the Liberator (like the springs and spring holder) but fully making it his own. His main goal for the design was to fire multiple shots without the need for reloading .22 caliber bullets. The Yoshee Six Shooter has seven 3D printed parts and a few required non-3D printed components including a brake line, a nail, and a screw. He has not fired live rounds from the gun, but has successfully test fired .22 blanks. Read about Chris' design over at 3DPrint.com: http://3dprint.com/93148/3d-printed-semi-automatic-gun/
