I tried printing a classic frisbee, but I found out, that the standard edges won't be strong and flexible enough, so I've adjusted them, so that the frisbee is as flexible as possible without losing durability. I've tested it outside and it flies much better than I expected and it withstood quite some torture, before it cracked (of course, it will never be as strong as inj. molded frisbee). 

The slicer settings I've used:

• Perimeters: 5
• Infill density 100%, first 3 layers default infill, then 2 layers concentric, the rest default
• Random seam positioning - no single weak spot

The rest was kept default

I used petg, as it's perfect for this, idk about pla, but anything stronger should be perfect.
