D Ring - for adjustable mask strapping

When I needed to create a strap for my growing collection of masks and helmets, I was looking for the ideal way to create an adjustable strap. A well known internet delivery company wanted too much for these, so I created my own!All you need is some elastic tape and a glue gun. From there, you can create your own elastic strap that can be adjusted.Included is a print file for the A1 mini.I tested the infill from 5% to 25% and each was sufficiently strong enough to hold the strapping in place and not buckle.Re-works welcome.
