After several years of duty, my Flower ring holders stopped working. Hopefully this design helps others as well!

I decided to replace them with a little bit bigger onces for extra stabability.
The inner ring contains 4 small “ribbons” to keep it in place better. The whole source OpenSCAD file is parametric, so you should be able to alter it if it might not fit exactly for your case.

Printed mine in ABS for extra durability and toughness, but PETG will probably also do well.
