A simple square tray (210x210mm) that you should be able to scale pretty well to any size and matching round coasters (100mm diameter) that fit well on the tray. Print with the infill design of your choice and zero top layers to expose the infill. I used simple triangle at 20% infill for the tray and cubic subdivision for the coasters, though I'm worried cleaning might be a hassle with the coasters.
Cheers!
