QR + text as a separate color part, ready for multicolor printing.
Scanning connects compatible phones directly to this WiFi network.
Two colors are mandatory: base = color 1, QR and text = color 2.
Default size is 85 × 55 mm. The back side is embedded into the first layers so the card still prints flat.
3MF contains both aligned parts and two material colors. The STL files use the same origin.
