Check out the latest and greatest gear from the third day of the 2014 Winter NAMM show.

Viktorian Guitars brought this 3D-printed Steampunk guitar to NAMM. The body is made of nylon, cadmium, and aluminum alloys—though they can be made from any substance that can be liquified—and the gears and piston operate with a 9V battery. It goes for about $4,500.
