If your 3D printing game gets strong enough, you, too, could be turning plastic bottles into $458 designer lamps. That’s exactly what Swedish studio Manu has done with its new line Teen Jane. Printed from recycled PET, each lamp comes with an “adoption” certificate, charmingly noting its past life as humble packaging. And thanks to a built-in dimmer, the lamp doesn’t just light up a room—it sets the mood. Eco-chic never looked this luminous.
