About this 3D model

A doctor my wife goes to needed a better solution than her current facemask so I printed the Prusa Face Shield, but then realized I could just design an AnyStrap that would work as the elastic head-strap, so here is that design.I've heard good things from the doctor who also takes this with her now when traveling also. =] I tried to accomodate most head sizes but if you print it and it's not large enough comment or send me a message and I'll design a longer one and add it. Lastly, these can of course be used for other things besides a face shield. Anything you can come up with!
