This is a slim cash strap replacement for the Ridge wallet. It holds an AirTag which can be easily clipped in and removed again for battery changes. I removed the battery cover to make the holder thinner, this will make the Airtag weaker against fluids, dust etc.

Battery sizes

This holder will work with the included (and more common) 2035 battery type, this will make the holder 6.7mm thick. Also the bottom will bend a bit, which shouldn't affect it by any way.

I recommend using 2025 batteries, as those will fit perfectly in the holder and result in a slightly slimmer variant which sits flush against the strap itself. This results in a 6mm total thickness.
