Will a 3D printed QR code actually scan?

Yes, if the two colours contrast strongly and the code sits at least 0.6 mm above the base. Both are handled by default.

How do I make a WiFi QR code?

Open the WiFi tab above the input, type the network name and password, and choose the security type: WPA/WPA2 for most home and guest networks, or None for an open one. The form builds the code for you and handles characters such as semicolons, commas and quotes in the name or password. Tick Hidden network if the name is not broadcast. iPhones and Android phones both offer to join the network when they scan it. Anyone who scans the code can read the password, so print it for a guest network rather than your main one.

Why 3MF instead of STL?

3MF stores colour inside the file, so each part opens already assigned to the right filament. STL carries geometry only.

What size should the printed code be?

Bigger than feels necessary. A scanner needs several pixels per module, so a long URL packed into a small plaque becomes unreadable even when it looks fine to the eye. Shorten the link first if you can; fewer characters means fewer modules and a code that scans from further away.

What if my printer is single colour?

It still prints. The code will be one colour and harder to scan, so raise the contrast by pausing to swap filament at the layer change.

Will custom colours or a logo stop the code from scanning?

Keep the code colour darker than the background — a scanner reads contrast, not hue. Adding a logo raises the code's error correction automatically, which is what keeps it scannable with part of the pattern covered. These choices only change the flat PNG/SVG image; the 3D piece always prints in two colours with the full pattern, logo or not.

How it works

Paste your link

A menu, a review page, a WiFi network, an Instagram profile — any URL or text.
Pick the object and two colours

Desk stand, keyring or wall plate. One colour for the base, one for the raised code.
Download the 3MF and print

Open it in your slicer. Each part arrives already assigned to its filament.

What people print

Restaurant menus

A desk stand on each table that opens the menu, with no laminated card to reprint.

Review requests

A plate by the till pointing at your Google reviews page.

Guest WiFi

A wall plate in a rental so guests connect without typing a password.

Event keyrings

A batch of keyrings that open a schedule, a form or a shared album.
