NFC Tag - Customisable (STL's included)

STL files are included for both the example of a plain NFC tag (which can be customised), and one with contains the Instagram logo. 

I wanted to create a design which did not require a pause to insert the tag, and where the 2 parts would clip together snuggly without the need for glue. I created a interlocking mechanism which works reliable when printed with the current print profile at 0.16mm layer. It clips together very satisfyingly and I would love to hear if this works as well for your prints also.
