QR Forever

No expiration date

Free 3D printed QR code generator

To make a 3D printed QR code, enter your link or Wi-Fi details, pick an object (table stand, keychain, or wall plaque), and download the 3MF or STL. The code is a raised relief on a base, in two colors. Your data never leaves your browser, and the code 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.

From link to printer

How to 3D print a QR code

You need a two-color-capable printer or a filament change.

1

Enter your content

A link, Wi-Fi network, or short text. 3D objects take up to 220 bytes, so shorter content gives larger, easier modules.

2

Choose object and size

Pick a stand, keychain, or plaque and a width from 40 to 140 mm. The tool shows dimensions and warns if modules are too small for your nozzle.

3

Download and slice

Get the 3MF (two materials, in millimeters) or the STL pair. Check the layers in your slicer, then print and test the scan.

Before you press print

Getting a 3D QR code to scan

Contrast is everything

Use a light base and a dark relief, or the reverse with strong difference. Low-contrast filament pairs are the main reason prints fail to scan.

Size modules for the nozzle

We aim for at least three nozzle widths per module. A short link means fewer, larger modules.

Honest about testing

The tool checks the code digitally. Physical print, slicer, and scan tests are not lab-verified, so always scan a real print.

Never expires

The data is inside the object. There is no redirect to maintain and no subscription.

Common questions

About 3D printed QR codes

The questions makers ask first.

Which file should I use, 3MF or STL?

3MF keeps millimeter units, aligned parts, and material colors in one file. The STL option gives two files in a ZIP, which you import together as one object, in millimeters, without moving them.

Can I print it with a single nozzle?

Flat objects (keychain, plaque) have a 3 mm base, so you can pause and swap filament at that height. The slanted stand needs a multi-material workflow.

What does the 3D object limit mean?

To keep modules printable, 3D objects accept up to 220 bytes and 77 modules per side. Longer content works for flat PNG or SVG images, which allow up to 535 bytes.

Can I add a logo or symbol?

Yes, in the center, up to about 15% of the width. The tool rejects a decoration that interferes with the code and simplifies logos to two colors.
