Houston Astros Logo coaster. Not 100% exact for the H, but real close. For holder use this: http://www.thingiverse.com/thing:979703Printed in 0.3mm, 10% infill. Start out with White until it starts outlining the letter H, then switch to orange. When star is complete and it's starting to be outlined like the H was, switch to navy blue. Once navy blue has finished it will start the coaster lip and then you switch back to orange. *Note - there is a small design error I'm trying to fix - the blue has a very small part inside the of the top of the H where the bars are, these can be easily broken off with no detriment to the current design.
