This is a surgical mask strap that is meant to relieve any discomfort felt by medical staff constantly using surgical masks. The strap is placed behind the head and the straps on medical masks are placed around one of the edges on the strap depending on head size to reach optimum comfort.
Thid is not an essential medical device but it assists medical workers who work long hours to save lives. This design is simliar to many of the other mask straps, but I designed this one to be the fastest to print, so each strap can be done in about 13 minutes. Please print these to assist our medical workers all of the world.
