Description
This is a multicolor WhatsApp-style keychain designed to embed an NFC tag inside the print. The model includes a dedicated 24 mm recess where the NFC sticker/tag is inserted during printing, so it ends up sealed and protected inside the keychain.
The project can be printed in multiple colors (3MF if included), and you can also use the separate STL files to slice it your own way.
After printing, program the NFC tag with your WhatsApp contact link (click-to-chat) or contact card, and share it with a tap.

To store your WhatsApp link/contact on the tag, you need an NFC writing app on your phone (Android/iOS).
