This key-ring is a derivative of one of our lamp designs 'Hexagon Overload' [see on Instagram link below], It could be used as shown as a key-ring and also if you want to play with scale in your slicer and print two they would make a cool pair of earrings. The models shown have been printed on an Ultimaker 2+ with a 0.6mm nozzle at 0.3mm resolution for speed, Therefore they can be scaled down easily by a factor of 1/3 for a 0.4mm nozzle and the quality can be greatly improved. We would love to see your prints! Follow us! F: facebook.com/3dppa I: @3dprintproject.athens
