I took http://www.thingiverse.com/thing:1946 and combined it with http://www.thingiverse.com/thing:195468 for a nice easy to print snowflake coaster! :)

PS: the little dent under one corner (can circles have corners?) is intentional. It's there to help you lift this off your build plate. Cause for me, something big wide and flat is quite difficult to remove without something to help get the separation process going.

I sliced with Craftware 1.13. Pretty default settings, with cheap white PLA and printed at 60 mm/s since this is a larger part and doesn't require super high tolerances on the output dimensions.
