Single Piece Easy Print Zipper Pull

I wasn't happy with the 3D printed zipper pulls I had tried because they were made with multiple parts that snapped together in some way, and would end up disconnecting after a few days of use. So, I made one that is a single piece. It's easy to print, requires no supports of any kind, and you can use just about whatever layer height you want. I do recommend setting up your slicer to print it solid with walls rather than infill. I printed one with PLA and one with PETG and they're both still going strong.

UPDATED: Now with version 2, which has a shape that is easier to get on and is slightly stronger.
