Lovevery Ring Stacker Replacement Donut

Replacement donut for the Lovevery ring stacker toy. I deep-cleaned my house not two weeks ago and had about fifteen of these things… now we're down to five. Printing more of them seemed easier than turning the house upside-down again. One day we might move house and I'll end up with a hundred of them in a box. The red and the dark green in the pictures are the printed rings. In the photos with the two red rings, the one in the foreground is the printed one and the one in the background is the original for comparison.
