Description

The next time, someone asks for your WiFi key, hand him this one and check how long it takes him to work out, that it has NFC. The key contains a NTAG213 chip that you can write your WiFi credentials to, using your phone. Simply scan the key to connect to your WiFi.

Things you need

NTAG213 stickers like those (affiliate link) (if they are bigger, you can carefully cut away a bit from the border, but watch out to not damage the antenna inside the sticker)

Recommended print settings

Layer Height: 0.2mm
No supports needed
Pause at height 1.5mm
Change filament at 2.5mm if your want the multi color variant

How to do everything

Start the print (include the pause and filament change from above)
On the first pause, insert the sticker
Optionally, change color on the second pause
Use the app “NFCTools” to write your WiFi credentials to the key
Optionally, use the same app to set a password for the NFC chip in order to keep others from changing the contents

Came out real nice. Also it is both functional and a dad joke. My sticker where to big but I increased the X and Y deminsions of the model by 2% and it fit fine. One warning. I have the P1S, I think it would be easyier to place the sticker on a bedslinger like an A1 or A1 mini.
