About This Tool
The Filament Mafia QR Creator is a free, browser-based tool designed to convert
standard 2D QR codes into high-precision 3D printable STL and 3MF files. Unlike
standard image converters, this tool generates native 3D geometry, separating the base plate from the
data blocks. This makes it the perfect solution for creating scannable multicolor 3D
prints on printers like Bambu Lab, Prusa, and Creality.
Step-by-Step Guide
-
Customize Your Code: Select your type (Website URL, WiFi Credentials, UPI Payment,
or Phone). Enter your data and watch the real-time 3D preview update instantly.
-
Adjust Geometry: Use the sliders to control the size, base thickness, and corner
roundness. Tip: A "QR Height" of 0.6mm to 1.2mm is ideal for clear scanning.
-
Export for Printing:
- Recommended: Click Download .3mf. This format saves the QR
pattern, text, and base as separate objects within a single file, ready for Bambu Studio or
PrusaSlicer.
- Alternative: Click Download STLs to get a ZIP file
containing separate meshes for manual assembly.
Frequently Asked Questions (FAQ)
How do I print in two colors?
Import the .3mf file into your slicer. The model will appear as a single assembly
with distinct parts. Simply select the "Base_Plate" object and assign a light color (White), then
select the "QR_Code" and "Text" objects and assign a dark color (Black). This contrast is essential
for the camera to scan the code.
Is my data private?
Yes. This tool runs entirely client-side in your browser. Your WiFi passwords and
personal data are processed locally on your device and are never sent to our servers.
Which slicers are supported?
The generated files are compatible with all major 3D printing software, including Bambu
Studio, Orca Slicer, PrusaSlicer, and Cura.
