This as a flying disc modeled after an Innova Disc Golf Champion TL Fairway Driver (7 5 0 1). :) I designed it from scratch and it's certainly not exact. The attached STL is 210mm in diameter which is the same diameter as the Innova. This disc is flat on the top as where the Innova is curved up to a flat surface. The black disc in the picture and video was scaled to 80% so it would fit on my print bed and it was modeled with 24 sides. The attached STL was modeled with 999 sides. Enjoy!Look! It flys! http://www.youtube.com/watch?v=Ft0o8aDtNakScale it to fit your printer bed if you need to when you slice it. I sliced it in Slic3r at 80%. If you have 200mm of space on your print bed, then divide 200 by 210 and you get 95%.
