The small but speedy 3D-printed flying drone called Micro Drone 2.0 will now make its design files freely available on its website, parent company Extreme Fliers announced today (Feb. 13). We went hands-on with the Micro Drone 2.0 at the 3D Print Show in New York City this week, where we were impressed not only with the drone’s design, but also with its smooth controls and speed. Created by Britain-based Extreme Fliers, the Micro Drone 2.0 is less than a foot across and has four small propellers that keep it aloft for up to 8 minutes and allow it to hover, turn and perform flips.
