3D Printing OhmEye's original design for a quadcopter frame. This one is done in ABS, 30% fill, 2 shells and 3 solid layers, .33mm layers x .4mm width. This is done real-speed. This particular design is very printable. No warping and only about 180mm square. This print turned out to be a relatively hefty 42.6 grams (compared to OhmEye's 33 grams for his PLA print).
The electronics and other parts to this quad are posted in the comments of http://www.youtube.com/watch?v=p0hRifI7V-Y.
