Cord Lock with Pen Spring (Kite String For COVID19 Mask)
thingiverse
I don't have access to a sewing machine, but I managed to print one of the Montana Mask variants online. Since I couldn't find an effective way to secure the string to my head, I created these cord locks myself. To use them, simply insert 1/2-2/3 of a spring from a ballpoint pen and it should provide ample tension to keep your mask firmly in place on your head. Stay safe out there!
