This is the Baha'i ringstone symbol. More information about this and other Baha'i symbols can be found here: Baha'i Symbols on Wikipedia

I print these at about 50% so I have included an STL for that size as well. Full size can be used as a wall decor. I've also included an SVG that can be used to cut out backing material. Please make sure that the SVG is sized to your print.

For a filament change, place a pause in your slicer at 2.2mm (standard quality) or layer 10.

I designed this by uploading an Illustrator SVG file into Tinkercad and extruding it into 3D. The original SVG files used are included.
