UppaBaby Vista V2 AirTag Holder

Traveling with kids, we often take our UppaBaby Vista V2 to the theme parks. One of my wife's concerns was always “what if they steal out stroller while we are in a ride?” Originally I used a lanyard and tucked it in underneath some of the fabric, but the air tag kept falling out, so I remixed this cup holder (https://makerworld.com/en/models/596180?from=search#profileId-518135) to suit my needs by holding an airtag as well.
