What is printpal 3D QR Code Generator?

printpal 3D QR Code Generator is a free browser tool that turns a web link, plain text, a Wi-Fi login, an email address or a phone number into a printable 3D QR code. The code is built at the highest error correction level, and a flat preview lets you test-scan it before you print.

You pick square, rounded or dot modules and a color for the code and for the background, then choose a raised code on a backing plate or a flat two-color tile. Sliders set the overall width (25 to 200 mm), how far the code sticks out, the base thickness and the quiet zone, and the outline can be square, rounded or a round coin. Optional extras add a keyring tab with a hole or an angled foot so it stands on a desk (not both at once), plus a frame with a banner for your own label of up to 24 characters, such as SCAN ME.

The 3MF keeps both colors in one file for Bambu Studio, OrcaSlicer or PrusaSlicer, the OBJ comes zipped with a material file, and the STL is a single solid. It is free with no watermark, but downloading asks you to sign in with a free printpal account. It suits guest Wi-Fi cards, cafe counter signs and keychain tags.

What you can make
