I printed a one leisure tag holder so I could attach it to the back of my phone with some double sided tape, I also added my email address which is embedded into the tag holder, either you can do it on tinkercad or I can personally do it on fusion.

If you would like to support me and help me buy more filament so I can test and make more designs, you can send money via paypal through this link: https://www.paypal.me/GeorgeElliott11
