Instructions
To generate your own personalized ring you need the MetaCAD AoI plugin - which is still in beta mode. If this does not scare you the plugin can be found here: objects.reprap.org/mediawiki/index.php?title=Builders/Metalab/AoI_MetaCAD
For all the others I included two generated STL files of rings with:
24mm inner diameter
1mm wall width
7mm height
in two variants: One has stars the other hearts embossed on the outside.
I also uploaded the star dxf file that parametrized the heart ring :)
