Mask Relief / Ear Saver

After printing [this mask](https://cults3d.com/en/3d-model/tool/covid-19-mask-easy-to-print-no-support-modified-version) I discovered that I did not have any elastic and had to use paracord I had on hand. This was pretty hard on the ears, so I made this to have the straps attach behind the head.

Should work for any 5mm or smaller cord, elastic or not. Because of the size you may need to extend the cord to fit. Allows for the straps to slide a little, which is different from most of the mask extenders out there, but at the cost of much higher print times. If you wanna help people, don't bother with this. This is pretty much only good for slightly improved comfort.

Nonremovable version should have one strap pass through the hole, making the piece permanently attached. Removable version just clips on to both straps behind the head.

F3D file included if anyone wants to make changes/improvements such as changing the length or hole sizes.
