Respirator string strap

Another way of producing a strap for the respirator (or other things). I used 1.75mm TPU filament, which was also used to print the respirator, as a mask strap although string or elastic would probably work as well.

The simple tensioner part included allows you to tighten the mask to your face and is relatively easy to use (particularly removing) as long as it is installed correctly (see pictures). You simply need to twist and pull the tab along the string to tighten it, and push down the string to loosen it; it works in the same fashion as a tent guide tensioner.

I have also included a STEP file and the original Fusion 360 file if you wish to alter it.
