WiFi QR Code 3D Generator
Create a QR code with your network name and password, and download it as a 3D-printed wall plaque. Guests or customers connect by scanning — no reciting the password, no sticky note on the router.
Create my WiFi QR code →Who this is for
Airbnb hosts, guesthouses, cafés with guest WiFi, or anyone who's tired of repeating their home network password to every visitor — a WiFi QR code solves it at a glance: scan with the phone camera and it connects automatically, no typing required.
Why 3D instead of just a screen
A PNG WiFi code works for printing on paper, but paper peels off, gets wet, or goes missing. A 3D-printed wall plaque with the QR code embossed in two colors (base and code) stays put with the two mounting holes built into the model, lasts for years, and looks a lot more polished than a laminated sheet.
How it works
-
1
Enter your network details
On the "WiFi" tab of the generator, type the network name (SSID), password, and security type (WPA/WPA2 is standard).
-
2
Choose "Wall plaque" and adjust the size
The tool calculates live whether the module size is large enough to scan reliably; enlarge the piece if it warns you in red.
-
3
Download the 3MF and print
Open it in Bambu Studio, PrusaSlicer or Orca Slicer — base and code already have their colors assigned. Hang it with the two mounting points.
Frequently asked questions
Is it safe to put my WiFi password in a public QR code?
The QR code only lets the scanning phone connect to that specific network; it doesn't display the password as plain text unless someone extracts it with a QR reader built for that purpose. If you're concerned, set up a separate guest network and generate the code for that instead.
Does it work with hidden networks?
Yes, check the "Hidden network" box in the generator before downloading.
Can I change the password later?
The code is fixed to the details you entered when you generated it. If you change the network password, you'll need to generate and print a new plaque.
Do I need my own 3D printer?
Not to generate the file — the tool is free and needs no printer. To print it, yes, you'll need a 3D printer (your own or an on-demand printing service).
