Rings you can use to pony up your Singstar microphones. Just unscrew the top of the microphone and swap out the original red or blue rings with one of these rings.
The cutiemarks currently featured in these files are: Pinkie and Maud Pie, Lyra, Derpy, Luna, Celestia, Octavia and Vinyl. Let me know which cutiemarks you also want to see here so I can add them.
A Step File and a Fusion360 archive is included in the files to enable you to create your own rings. Just import a vector of a image you like and extrude it into the outer layers of the ring. There are three different layers to be able to achive a 3D effect of the imported vector.
