I made these 2 piece coasters so that condensation will drip through the top part and collect in the bottom part keeping it off your table and keeping the bottom of the glass dry.
I printed the top part with 0 top and bottom layers and 20% Gyroid infill.
If you want a set and don't fell like printing them you can find my shop on Etsy under Hexware.
