Just a simple elsecaller coaster
You can print only the coaster and paint the grooves (I dilute some acrylic paint in water and add put it in the groove with a syringe)
You can also fill the grooves with epoxy or UV resin(In my experience this opction is the best)
You can print the insert in other color and push it into the groove
In the insert stl i added an little circle to merge all bodies so they keep toghether dont worry about it when you slice it it will disapear
