3D print (STL)

Diameter mm Base mm Relief mm

Two aligned solids sharing one origin: print the base in your plate color and the top layer (code + ring text) in your code color, or merge both in the slicer for a single-color embossed coaster. The center logo image isn't included in the STL — place it in the slicer if you want it in the print.

The scannable code stays square — plate shapes frame it and the light border is the quiet zone. Download the SVG (ring text ships as real outlines, so slicers and CAD tools keep it) or export STL directly for printing.
