Smallest AirTag Keyring

This is, to my knowledge, the smallest and easiest printable keyring add-on for Apple AirTags, perhaps only in contention with: https://www.thingiverse.com/thing:4854066. It leverages a .4mm gap between the main body and the battery cover to very securely stay in place without affecting overall thickness or the primary diameter. To install the attachment, remove the battery cover and place it in the printed keyring holder, and reattach the battery cover to the AirTag as usual and you're done!

The design can be printed in less than 5 minutes and should fit just about any keyring, lanyard, etc.
