A 3-D Printed Frisbee made by the Makerworld AI Photo to Model tool (https://makerworld.com/en/makerlab/imageTo3d?from=makerlab) with slicer settings modified by me. 

The first time I just took the model and printed it. I threw it and… it flew! Then, my sister wanted to try, so she picked it up and threw it high in the air, it came back and landed straight on the driveway and cracked neatly in two. Normally, I'd be mad at her for this (sibling rivalry, after all!), but this taught me a lesson: the frisbee needed to be stronger. I realized the print lines were in such a way that it they split cleanly when cracked, so I oriented it at a 45 degree angle to put the lines diagonally so it won't crack in any orientation. And thus, the frisbee was ready for MakerWorld! Enjoy!

Make sure to print at a 45 degree angle so that the print lines do not crack easily.
