I really liked this design but it didn't fit the hair ties I already had, so I shortened the hair tie paths to fit them better. The hair tie paths are also cleaned up to remove an overhang in the middle. I added a chamfer to the top and bottom for ease of printing and to improve the feel of it in your hand.
I've also made a bunch of variants, some inspired buy the original author's designs and some of my own. My personal favorites are the Hex Border ones, so check them out!
