Check out this unique and useful 3D printed gadget:

The gadget, designed by an Athens, Greece-based maker and prophet of what he refers to as the “Next Industrial Revolution”–3D printing or additive manufacturing–is digitally designed and then 3D printed in stainless steel (420 stainless steel alloy with infused bronze–40%). It’s about the width of a cigarette, although a bit shorter. The designer, who’s Etsy Shop, InnovoDesign, offers the pieces for $63.58 each, says he most enjoys creating “functional, innovative, unique objects and artifacts.” We agree that there’s something kind of retro and mysterious about this gadget. The texture of the stainless steel and the shape of the object are evocative of the Art Deco style. 3D Printed, Radioactive Tritium Flashlight Runs for 20 Years Without a Battery - 3DPrint.com
