Face Shield Strap for Brüssel888

My wife works in food manufacturing and needed some printed visors that could be worn for an extended period (min 8 hours of near constant use). As they would be worn in a factory environment where preventing physical contamination is a high priority, I could not use elastic bands or any kind of cloth strapping.

While the Brussel888 design is amazing, testing them being worn for long periods without a strap, they would hold in place for about an hour or two before they started to slip.
So I've designed an adjustable strap to work with the loops on the back of the headband.
Printing these (or any PPE items) in any filament that contains metal powders means that if they DO break and find their way into the food products they will be detected by food manufacturing factory's mandatory metal detection procedures.

I hope this design can be useful to someone! Stay safe!
