Designed this coaster, because I wanted something tidy looking and dual color, without filament changes

Neat. What plastics lack in absorbancy, this might make up for by having wells where condensation could drain into. Could also prove a veritable mold farm I suppose. Might try this with tpu as mesh layer to reduce slipperiness.
I've made similar coasters a while ago, just with a stone tile as the base. Despite having to endure a cup of hot tea every day, it's holding up very well so far and stays clean.
The PETG did minimally deform after months of using it, which is both good and bad. On one hand it's now formed in a way that perfectly fits the specific cup I use, but that also means that it's become a bad fit for every other cup or glass.
Your comment about using TPU has given me the idea however to make the tile reversible with the current PETG on one side and Flex material on the other.
That is why I regularly disassemble mine and toss them in the dishwasher to prevent mold and to clean them from dust and drinks.
Does your dishwasher have a cold wash setting or did you print these in ABS or something?
It has a 60°C short program. Fiberlogy PETG doesn't warp at those temps.
Gotcha. I'm not sure I've ever had a dishwasher with that functionality.
