This design was made for laser cutting in CorelDraw, which only runs on Windows because Corel hates freedom and baby animals. Formatted for cutting/etching using NYC Resistor's Epilog laser cutter. Blue lines are set to cut, and any fill is set to etch. More info on NYCR's laser wiki: http://wiki.nycresistor.com/wiki/Laser_Power
Acrylic used can be aquired at eStreePlastics: http://www.estreetplastics.com/Black_Plexiglass_Acrylic_Sheet_p/b013751212.htm. Recommended dimensions are a 12"x6"x3/8" sheet of black or transparent black plexiglass.
The longer ends of the two temple arms (sides) fit into the holes in the visor (front), but may require some acrylic weld if the laser melts off too much from the hole edges or if the acrylic is too thin.
