To build this, you'll need a 3D printer, some ABS plastic, acetone (for aerodynamic glossy finish treatment), a large glass bowl (acetone vapor chamber), and about two hours. To test these blades, you'll need a quadcopter which uses four or six hexagonal (6x2.5mm circumference) propeller inputs. The list of recommended settings for the 3D printer software, as well as other instructions can be found on Thingiverse here: http://www.thingiverse.com/thing:1060181
