Chìa Khóa WiFi NFC Hai Mặt

I remixed the WiFi key from Molodos to add the NFC logo to the other side. This will make it a bit easier for your guests to figure out what to do when you give them the “WiFi key”.

The key contains a NTAG213 NFC chip. You use your phone to write your WiFi credentials to the chip. Simply scan the key to connect devices to your WiFi.

Items Required

• NTAG213 stickers  - 1 inch or 25 mm diameter

Recommended Print Settings

• Layer Height: 0.2mm
• No supports needed
• Pause at height 1.8mm to insert the NFC tag
• Change filament at 0.8mm and 2.6mm to for multi-color accents

Instructions 

1. Slice the file - including the pause and filament changes detailed above
2. Start the print with your accent color
3. At the first filament change, swap to your base color for your key
4. At the pause, insert the sticker and then resume the print
5. At the second filament change, swap back to your accent color
6. Once finished, use the “NFCTools” app to write your WiFi credentials to the key
7. Optionally, use the same app to set a password for the NFC chip to prevent others from modifying its contents. 

Additional Notes

Choose whichever side you want to be the top of the key and which side you want to be the bottom. The bottom side will have bridging. 

I've centered the NFC tag opening inside the key between the two key faces. The color changes and pause are the same no matter which key face you put on the plate.
