Baseball hat facemask clips

These are clips meant to fit in a baseball cap, to allow a face mask to be easily attached without straining your ears. I made these after being disappointed with what I got from

That design is a huge annoyance to remove or attach a mask, and I wanted something I could put on / take off more easily.

Please feel free to improve on this if you like.
