Took the hanging decoration, cut it in half, mirrored it, turned it into a coaster, i printed several of these in various sizes, all work very well.

took down the 2 part version as i have a single complete version now uploaded

This one was printed using Makerware Desktop,
settings i used for printing with pla are:

infill = 15% (i know this is high but it really does need it)
layer = 0.2
extreuder temp = 195
hpb temp = 60
speed = 40/70

i also upscaled to 110% this made a more riged and thicker print
