Covid-19 Faceshield Spring "Strap"

Quickly sketched this in Fusion 360 for our local COVID-19 shield printer group. It connects the back of the shield holder together to secure it better then elastic or the standard shield holder as is. Can be scaled up or down if needed for particular head sizes but should be useful for most. I have printed this multiple times without issue and fits comfortably in my and my girlfriends opinion.
