Did you know you can do automations based on NFC tokens? Here's a video showing how its done on iOS with an AirTag (which also has NFC built in).
This design fits 25mm / 1" NFC tokens (like this).
The back holds an 8 mm magnet (like this). It should press into place firmly and stay in place without the need for glue.
I've included a few design of different fronts. If you have a design you'd like please leave a comment (and even better, link to an SVG) and I will make another file for it.
Most people will use these on their fridge. They're also fun to attach to drywall screws that aren't visible in your wall.
Print with the threads on the build plate.
The author marked this model as their own original creation.
