NFC tag cases with magnet holder

Some NFC tag holder with magnet in it to fix your tages to metallic surfaces

I use the ‘flame’ model as a NFC tag to switch on/off my heat AC.
I use the ‘IRobot’ model to start my roomba on the selected room.

To use this model you must have :

-a generic NFC tag with a radius of 25mm (or under)

be aware that there are normal NFC tags that doesn't read well on metal surface, and other nfc tag made for metal surfaces !

-a magnet (6mmx3mm)

The model is paused at mid-print to allow you to put the nfc tag and magnet in it.

This is my first published model, it worked well for me but it may not be quite print efficient, please be indulgent;
If you have any advice feel free to make me know.
