I couldn't find a coaster thing that I liked so I made my own. I also wanted to play with the new translucent PLA colors from Makerbot that I had just received so I made my coasters as thin as possible to showcase the colorful translucency.

The ribs on the coaster provide rigidity at a low cost, reduce the contact area with the beverage container and for circular containers provides some resistance from slippage.

Total weight for all 10 coasters and the holder is 102 grams.
