StackableCoasters_Coaster_NoHole
Print as many of the coasters as you like. By adding some color to the coasters you can prevent mixing up the drinks.
There's also a “SingleGroove” and “MultiGroove” design which should be able to catch the fluids even better and prevent them from dripping through the center hole onto your furniture.
I use a similar design in my household and haven't had much issues with the hole in the center of the coaster, yet.
Howerer, there's also a “NoHole” version of the coaster. They are still stackable but you can't use the base with this version.
These coasters are large enough to hold a glass with a bottom diameter of up to 84mm. Feel free to scale it up or down.
Stackable_Coasters_Base_4C
Stackable_Coasters_Base_6C
