AirTag Backpack Web Strap Case

This is a protective case I made to attach an Apple AirTag to my son's backpack. I wanted to keep it securely attached to the backpack, but also keep it away from curious fingers so it didn't get lost. The AirTag fits snugly inside, and a typical nylon webbing backpack strap should fit relatively easily through the openings on either end, just undo the strap from the backpack buckle, feed the strap through and reattach to the buckle.
