Free QR code wall plaque for 3D printing

A QR code wall plaque is a flat 3D printed sign with two mounting holes that you can screw to a wall, door, or post. Enter your link or Wi-Fi details, pick a shape, and download the 3MF or STL. The code is raised in a second color and never expires.

You can also turn it into a printable 3D object: a table stand, a keychain, or a wall plaque.

Preparing your design…

3MF keeps the two colors per part. Assign the filaments in your slicer; automatic assignment depends on the program. STL does not keep colors.

Customize the design

Screen colors are approximate; assign real filaments in the slicer.

Your links, images, and data (Wi-Fi, contacts, messages, events) are processed in this browser and never sent to a server. The files you download do contain the information you encode, including Wi-Fi passwords.

Plaque in three steps

How to make a QR wall plaque

Decide where it will hang before choosing the size.

1

Enter your content

A link, Wi-Fi network, or short text. Keep within 220 bytes for 3D objects; shorter content gives larger modules.

2

Choose shape and size

Rectangle, rounded, or circle, between 40 and 140 mm wide. Add a caption or symbol outside the quiet zone.

3

Download and mount

Get the 3MF or STL. A 3 mm base with two 4 mm holes lets you use screws or sticky mounts. Test the scan before you hang it.

Made to stay up

Making a wall plaque last

Two 4 mm holes

Mounting holes sit outside the quiet zone. They have nominal size with no printer compensation, so check them against your screws.

Guest Wi-Fi at the door

The guest template sets up a plaque for sharing your network. Use a guest network to keep your main one private.

Wi-Fi QR code

Pick durable filament

For sunlight or outdoor use, choose a material that tolerates UV and temperature. The tool does not choose material for you.

Never expires

Nothing to renew. The data is inside the plaque, so it works as long as its destination does.

Common questions

About QR code wall plaques

What property owners and shopkeepers usually ask.

How do I mount it?

Use the two 4 mm holes with screws and plugs, or use strong adhesive pads on the back. Check that screw heads clear the code.

Can I print it with a single nozzle?

Flat plaques have a 3 mm base, so a pause and a filament change at that height can work. Check that it lines up with a layer in your slicer.

Can I use it outdoors?

It depends on the material and exposure. The tool designs the shape only. UV and heat can fade or warp some filaments.

Will the plaque scan reliably?

The tool checks the code digitally, but physical print and scan tests are not lab-verified. Print one, and scan it with different phones before you install many.
