UPDATE:

Please see the revised version that prints without supports and has better flight characteristics:

__________________________________________________________________________________________

This frisbee easily flies 100+ feet (large one 200+) on a good throw: use lots of wrist snap and point the front slightly upward. The smaller one will fit most printers while the larger one needs a 300mm x 300mm bed. Prints well and plenty durable with PLA+. You can also use ABS. Supports required and you will want to give the bottom of the frisbee a light sanding to smooth it out after removing them. Never be without an outdoor flying toy again!

If the frisbee rolls to one side while in flight, use more wrist-snap in your throw. Also, bending the frisbee up or down will help trim the disc to stop the roll.

I recommend .1 mm layer height to create a smooth airfoil shape.

Take a sanding block or a sheet of 300 grit sand paper and give the underside of the disc a good sanding once the supports have been removed.
