Summary

Needed a simple cinch to hold paracord (550 cord) easily so I didn't have to tie the paracord for cloth masks. This has enough friction to easily slide up against the back of the head and then hold in place.

For thicker 550 cord print at 100%.
For thinner cord I've had good success at 95%

The slot in the middle is designed to help push the paracord through.

I've included the fusion 360 file so you can edit it as you need/see fit.

Now that the pandemic has ended this is also handy for sacks, camping gear, etc.

Notes:

Print with small layer heights so the angles to help with flow print well.
