Swiss army keychain with space for nfc

This is another Swiss army keychain. I decided to design it to give space to hold a nfc key.

Details:
* Space for one nfc key, with hole to see it.
* Rough surface (circles) to improve grip and aesthetic.
* Adapter for a keyring to hold extra/temporary keys or hold/hang the keychain.
* Adapter for nfc made apart to avoid supports (or printed in another color). It needs to be glued.
* Three upper part versions:
* Without space for nfc.
* Wireless icon shaped hole.
