Smart Tag 2 insert for modular wallet

Here is my approach to Smart Tag 2 insert to popular Modular Wallet print.It is important to mention that the smart tag does not hold on its own and you gonna need some additional fixing. You can try same approach as me and add a little elastic band used for sewing (they cost few bucks in some sewing shops). I attached also f3d file so you can adjust it to your needs.
