Queensland Police Raid Home, Find 3D Printed Gun Parts

Queensland Australia Police stumbled on a bunch of 3D printed gun parts this morning as they raided a 28-year-old man's house in Mudgeeraba. In addition to the 3D Printed gun parts, they also found drugs, a sawed-off shotgun, a 3D printed pair of knuckle-buter and ammunition. Charges were brought on the shotgun and drugs, but they are waiting to confirm the 3D printed parts are in fact for the creation of additional weapons before bringing further charges. More information on this bust can be found here: http://3dprint.com/43542/3d-printed-gun-parts/

Below is a picture of the gun parts found. Do you think that charges should be brought against this man for these gun components?

well given that he had drugs and a sawn off shotgun - illegal in most of the world.
The gun parts are kind of moot.
Though it does look like he was mass producing the gun parts. And it's the one the japanese guys developed as well. With metal barrel and cartridge chamber inserts.

So yeah, it definitey comes under illegal arms dealing.
