You may know my original sunflower fabric coaster (https://www.printables.com/model/285153-sunflower-fabric-coaster). This is a LARGE version of it where an extra row of petals is added. There is a holder for them in the files below as well.
It is surprisingly very flexible and addictive to play with. Just be careful not to put your thicker fingers deep in the center, it's quite catchy ;).
