Wi-Fi → QR → STL Generator

A 3D-printable plate with your Wi-Fi network's QR code. Guests scan it with their camera and the phone connects on its own — no more reading the password out loud.

Exactly as in your router settings — case sensitive

Works in almost every case — most routers use this

Enable only if SSID broadcast is turned off on your router — otherwise some phones may fail to connect.

Corners are rounded by the radius below

A solid slab under the pattern so no light shines through the gaps between QR elements. 0.6 mm equals 3 layers at 0.2 mm layer height. Set 0 to disable.

// QR code

Blank margin around the pattern. The standard is 4, but the white plate around it already serves the same purpose. Lower it to 1–2 to bring the text closer to the dots and make the dots themselves bigger.

The model is flat (no raised bumps) and consists of two bodies — black and white — for two-color printing. The archive contains qr-model.3mf — open that one: both parts are locked in place relative to each other, you only need to assign a filament to each. The separate STLs are included for compatibility: if you import those, load the second file as a PART of the same object, otherwise the slicer will drop it onto the bed on its own and break the alignment.

Please noteThe password is embedded in the QR code in plain text — anyone who scans the plate gets access to the network. For a plate in a public place (café, office, lobby) it's better to set up a separate guest network rather than sharing your main one.
