I have been planning to make this model for a long time, the model complements my existing sunflower fabric coaster (https://www.printables.com/model/285153-sunflower-fabric-coaster).
The holder should hold 4 to 6 coasters.
For better portability, there are two cutouts for fingers on the middle stem.
If you need a lower or higher model, just try Z scale in the slicer.
