This is a Frisbee made for my grandson, Logan. Designed in MOI (Moment of Inspiration), and made in DiamondAge PLA on an Ultimaker. I was doubtful that it would print without support but it did, though it doesn't look that great even after a clean up. Flies well, though! 175 mm O/D, weight 31 gms.I found that a raft was essential. Brim (in Cura, anyway) only works on the O/D. I've made two. The second was slightly better than the first. For this my settings were 190 C, 0.1 layer thickness and 100 mm/s print speed. And a RAFT!
