e-clip for Facemask frame

thingiverse

https://www.thingiverse.com/thing:4262131 is a great facemask design. Many users don't have access to the phlebotomy tubes used as straps. Sewing elastic is scarce in the age of facemasking. I provide a 3D printable clip to allow use of elastic hair bands to attach to the facemask frame quite elegantly. You can either chain hair bands to achieve the desired length, or tie one band to each end of a cloth strip that is sized to fit snugly when the bands are stretched. Multiply the object when slicing as desired to print many per print. Since I don't have access to the Halyard material, I'm experimenting with blue shop towels, which others have found to have quite effective filtration when using 2 layers. Added cloth strap and 2 elastics option for saving the extra elastics for more shields. Adjust the strap appropriately to use the band stretch for tensioning.
