Another fabric coaster. This time circle shaped and inspired by sunflower seeds arrangement.

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 ;).

Do you need a holder for them? - https://www.printables.com/model/380230-sunflower-coaster-holder

By the way, here are two bigger sizes of this coaster:

EXTRA LARGE: https://www.printables.com/model/1012077-sunflower-coaster-xl

Printing: 

There are no special printing requirements, NO supports.

Printing tips:

1/ Use concentric infill for the top layer.

2/ To make smaller size use only XY scale in the slicer.

3/ To make larger size I would use XYZ scaling in the slicer.
