Four Elements Coaster

A cup coaster that embodies the four elements of Earth, Air, Fire and Water. After receiving a sample order of some thermochromic filament (changes colour with applied heat), I decided to make a coaster with swirl designs that would show the flow of heat from the cup. I should have designed it a bit bigger so I could actually watch the flow of heat, but instead I'll either have to use a smaller cup or just contend myself with lifting the cup to see what it's doing. Measuring 9cm x 9cm x 1cm in size, this will fit most average mugs and is designed to not require any support structure.
