3D preview
3D preview loads automatically when scrolled into view.

How it works
- Paste a URL or any text in the box above — the QR code updates as you type.
- Pick a shape (keychain, stand, or plaque) and a size; the 3D preview updates live.
- Download a two-color 3MF file, ready for AMS/multi-material printers.
Everything — QR generation, the 3D preview, and the exported files — is computed locally in your browser with JavaScript. Nothing is uploaded to a server.
Frequently asked questions
Does this tool store or upload my URL?
No. The QR code, the 3D preview, and the exported files are all generated in your browser. Your URL is never sent to a server.
Will the QR code still scan after it's printed?
It should, as long as the modules aren't too small for your nozzle. The tool warns you if the module size drops below the 1.5 mm generally recommended for a 0.4 mm FDM nozzle — enlarge the piece or shorten the URL if that happens.
I don't have a two-color or AMS printer — can I still use this?
Yes. Most slicers can open the 3MF and print it in a single color — either leave the raised code as-is (the relief alone is often enough contrast to scan) or paint it by hand afterward.
What if my browser can't show the 3D preview?
The 3D preview needs WebGL. If it's unavailable, the QR code and the exact measurements are still shown as text, and the export button still works.
