Here is a strong and compact holder for the Apple Airtag. Made to suit any keychain / keyring.

It's one of the most compact holders yet one of the strongest. The design is simple and uses the material's strength and flexibility to hold the Airtag in place.

I designed this holder to make sure it will not pop out !

The metal cap stays accessible in case you need to change the battery, no need to remove the airtag from the keychain.

Printing instructions

I recommend using PETG or PLA.

I recommend printing at 0.2mm height for better results and finish.

Print it on its backside, no need for support (see screenshot).

Get it printed and shipped to you

If you don't have a printer, I uploaded it on Shapeways, so you can get it printed for you, plus the finish will be much better and you have the ability to order many.
