This is a cord lock to use paracord with the Montana Mask.you will need to print 2 half bodies and a lock to make this thing. I am including the stacking 2 files and the stacking 160 bodies. I also included various sized cord locks so you can adjust this to work with whatever quality of paracord you can get. Each mask uses approximately 4 feet of paracord. 2 foot loop for the top and a 2 foot loop for the bottom strap of the mask. I use a small zip tie on each open end of the cord to make a small loop. I then zip tie the whole thing using the printed loops on the mask and zip tying them to the loops in the cord. Each mask will require 2 cord locks and 4 zipties.

Even though it works just snapped together, I use a soldering iron to melt the top to the bottom to insure that they wont come apart.

When you use these, the mask will hold to the wearer's head very tightly. To remove the mask, just slide the thumb knob on the lock to release and pull it back.

I designed these because I could not figure out an easy way to hold the masks to the wearer's face. I have worn this around town for the last couple days and it works well. I have donated a lot of these to my local hospital.

here is a short video of how it works... https://youtu.be/BKhKK8FuA28
