The coasters of 4 elemental dragons - Earth, Wind, Fire, Water (地風火水), braced by dragon scales. In Buddism, these 4 elements constitute matter and everything in the physical world. This is in combo of my other design - the dragon box of Wholeness (https://makerworld.com/en/models/130439).

I have to separate these into 4 profiles because the Arachne slicing makes it too long to slice if 4 together. I suggest changing the top infill into Monotonic and the solid infill into Monotonic Line.

I added another profile if you just want the 4 coasters to be the same colour, it is faster but you might lose some detail.

The layer heights are separated for two colours.
