3D printed QR code generator — free .3mf export

A free 3D printed QR code generator: create or scan any code and brickcodes exports it as a .3mf file — raised modules on a studded plate, in two colors, ready for your slicer. No LEGO needed, and it still scans.

Create your 3D model

What you get

Create or scan a QR code, then download a .3mf model of it. The dark modules are raised on a studded baseplate, trimmed to the code plus a quiet zone so it stays scannable. The file opens in any modern slicer — PrusaSlicer, Bambu Studio, OrcaSlicer, Cura — and on FDM or resin printers alike.

It prints in two colors

The piece and baseplate colors you choose are embedded in the file, so a multi-material printer reproduces the contrast that makes the code scannable straight off the bed. Printing in a single color works too — the raised relief still reads under good lighting.

Pick a size for your printer

Choose Compact, Standard, Large, or XL — from roughly 60 mm up to about 165 mm square, depending on the code. Every size fits the beds on common printers like the Bambu A1, Prusa, and Creality Ender, and you can rescale further in your slicer.

It matches your LEGO style

The model mirrors the brick style you select: smooth tiles, studded plates, taller bricks, or round 1×1 plates. So a 3D print can stand in for the LEGO build, or serve as a prototype before you order parts.

Prefer to build it in LEGO?

That is what brickcodes does best. Generate a build for an exact parts list and a BrickLink wanted list, or make a LEGO Wi-Fi QR code for guests.
