NFC Keychain

I quick modeled this NFC keychain on Autodesk Fusion.

You just need to buy some NFC tag stickers (this model is designed with 25mm round stickers in mind), print this model with a pause just before the “closure” of the hole in the keychain for inserting the sticker embedded in the model and you're done! 

After that you can use any NFC tag editor app (I used NFC Tools) to insert any link needed, for example social medias or LinkedIn accounts.
