This 650 hexacopter is printable of a standard 200 by 200 mm 3d printer. The design is based on the Spyda 500 Hexacopter mixed with the Tubular Crossfire 2 quad-copter. The tubes arms were originally designed by Member Brendan22. I printed the top and bottom plates with .4 infill. The arm tubes with ,4 . The motor mounts i printed solid. I don't know why but To get the arm tube to fit in pronterface I had to rotate it 90 deg. in sicer.
