Spotify Keyring Inspired by The Fifth Element stones

Hello! I designed this keyring inspired by The Fifth Element movie stones. It can be printed without supports.

I added a custom Spotify code that currently points to the Hakuna Matata song. I have never shared an editable file before so let me know what file would be useful to allow you to add your own custom Spotify Code. 

I also have seen some customizable models, but I have no idea how to make that. If someone can guide me to achieve that I will be happy to make my model customizable. 

It was originally made in Fusion 360.

Edit: People suggested me to share a .step file so it can be customized. step file has been added! 

Enjoy!
