Disc golf holder for discs designed for bags without a flat bottom. It will hold discs of a max diameter of 212mm (8.3") and a max thickness of 24mm (.95"). The bag I use is the Adidas Alliance II. This is a large sports bag so the holder probably won't fit in a normal drawstring sports bag.

I printed the holder with the slots up. It did not need any support except in the rounded corners of the sports bag.
