Face mask ear loop tensioner and comfort piece

cults3d

With homemade face masks becoming ubiquitous, and thinking about the discomfort of having a loop around your ear, as well as the supply of elastic running out and forcing people to make the loops out of non-flexible string, I made a simple piece that when printed (x2) uses a rubber band to pull the earloops of a mask in tension and off the ears, keeping the mask snug to the face, and comfortable over long periods of time. I made the loop side of the piece with a flange to help retain the loop string so that it does not easily fall off when putting the mask on or taking it off. See pics. There are two sizes of the flange opening to accommodate for different thickness of materials used for the mask ear loops. The "thin" version for smaller straps, and the "thick" version for larger straps. You can also simply scale up the model in your slicer program for even larger material if necessary.
