HeadStrap Y Bracket

My first educated (completed the "Donut") attempt at designing a part in Blender. Printed a Covid mask and was not thrilled with the way it fit when I just tied nylon cords around it with a simple printed clasp at the back. There was no "give" and it kept slipping out of place. The Y bracket makes it so that the 2 cables can cradle the head and stay in place, elastic gives it the right amount of give. It was made to fit 4mm nylon cord and 1/2 inch elastic on the other side. I couldn't find anything like this on any site, so I made it. Hope it helps you, or inspires you to make something that fits you (pun intended) better.

Length 42mm
Width 43.7mm (big side)
Width 18.6mm (narrow side)
Holes 5mm
Elastic rectangle hole 10mm

I've never posted this before, so if there's something I didn't include, reach out and I'll try to answer. Happy Printing!
