This holder fits an Apple Airtag and a Yubico Yubikey 5C NFC and should fit the most wallets.
Print exactly like defined in the 3mf. I recommend to use PLA as you need the holder to bend a little when inserting the Airtag. If you like you can play around with the infill to change the pattern.
Note there is only one right side to put the airtag in: the wider circle. Apply a bit of pressure and it will snap right in.
Edit: On Request I also added a version for the Yubikey 5 (USB-A)
Feel free to support my work :)
