Printing it
This needs two contrasting colours. The code scans because it is dark on light, so a one-colour print will probably not work.
Multi-colour printer: “STL per colour” gives a zip with a file per colour, in the same position, to load together. The 3MF has the colours set already, for slicers such as Bambu Studio.
