A friend of mine was making these headbands to help nurses keep the elastic from their face masks off their ears. But she ran out of buttons and they're sold out in a lot of places, and can't deliver for a couple of weeks. So I designed some buttons and 3D printed them for her to use.
There is a two-hole and a four-hole version. it's about 1" wide; scale down 75% for a 3/4" version.
