Grizzly 2.0 designer says CAD files to be made available soon for download.

13-aug-3D-printed-rifle-360Adding to the controversy of 3D printed weapons, a Canadian designer known only as “Mathew” recently posted YouTube videos of himself test firing the Grizzly 2.0, a ABS+ plastic, 3D printed rifle he design himself in Solidworks and produced using a Stratasys Dimension 1200ES printer. Inspired by Defense Distributed Cody Wilson’s Liberator 3D printed pistol, Mathew is shown in the video firing 14 .22 calibre bullets before the barrel shows signs of cracking.

Named after the Canadian WWII tank, the Grizzly 2.0 is an improvement from the original, which made its Internet debut in July but cracked after only one firing. According to Mathew, the new version features a thicker tapered barrel, a larger receiver and internal rifling.

While functional, Mathew has said the Grizzly is difficult to load and is generally unwieldy but will improve as he continues to work on the design. Description of the Grizzly on his YouTube account (ThreeD Ukulele) says he plans to post the CAD files for printing the Grizzly soon.
