Assembly (Important)

This part is very simple at the cost of needing some extra materials.

1. Attach to the case
   I used, and recommend, hot-melt glue. Liquid adhesives may work.
   Apply a small amount of glue in a circle on the bottom surface, and hold firmly against the bottom (or top) of the earplug case until the glue has cooled.

2. Add a springy / cushiony material, like foam, to the center hole
   I used a small cut of a rubberized shelf liner. A firm foam should work too. This serves to hold the battery against the AirTag's contacts.

1. Remove the AirTag battery cover
   Press down on the AirTag's original metal cover and turn counter-clockwise to remove. Keep it in a safe place in case you need it again later.

2. Press the AirTag body into the printed piece.
   The flat (+) side of the battery must face the case. It should firmly clip into place, and you should hear a sound from the AirTag confirming it is powered on. If you do not hear the power on sound, go back to step 2 and add more/different material.

3. Checks
   Give everything a shake to make sure the battery stays in contact.
   Firmly tap against a hard surface to ensure the AirTag holds securely and will not come out.
   If the AirTag makes the power-on sound when you shake it, there is not enough material holding the battery in place. If the AirTag pops out when firmly tapped on a hard surface, there is too much material.

Other Information

I was going to way over-engineer this. I found simply adding a hole to an existing model to be a much simpler solution, but I'm sure it's far from the best solution. This was a compromise, as I don't have the exact geometry of the case.

Compatible with both the new style case with a silicone insert, and the older, smaller case with felt on the inside.

Not tested for water resistance. Printing in PLA is not recommended, as it will loosen up very quickly.

To pop out the AirTag and replace the battery, use a small tool such as a guitar pick to gently pry it out.
