Reservoir coaster set with holder

thingiverse

How come most coasters are flat and made of something non-absorbent so they're only useful at times when you don't need a coaster? Try using one of those when there's some humidity on a summer day and your drink is cold, and you end up with a puddle spilling over the edge and defeating the point of having a coaster. Even the ones made of absorbent stone don't absorb enough. Cork ones do all right but tend to get pretty ratty and even smelly, and they're hard to find. I saw Stanistani's coaster idea and liked the concept of a coaster that had ridges for the moisture to seep into, but people said in reviews that the little bumps didn't do that good a job holding up the cup. So I decided to make an approach that would have a bit more rigidity at holding up a cup, but still have room for it to drain condensation. Plus concentric rings just look cool, stylistically speaking. I also made a holder that stores six of the coasters stacked since they don't otherwise have any way of keeping themselves in a tidy pile. Instructions A simple print with a bit of a brim to avoid warping. Print six of the coasters plus one holder for each set. Same color or contrasts? Good question! I'm tempted to have a white holder and a red, orange, yellow, green, blue, and purple set, but maybe all one color would be more tasteful. I've printed one set in blue at 100% scale which fits most of my glasses and cups, and one set in black at 120% scale which fits the bigger plastic tumbler cups.
