Summary

I have a friend who loves pirate lore, so I took the great D and D coasters by Brzam and combined it with Pirate Doubloons by runner409. Also pictured is the holder by jbwill237.

I inserted a fliament change at layer 11 so as to print the base in black and the skull and cross bones in white. Other color combinations can be used, of course. I used stone color filament for the holder.

TinkerCAD for the design and Cura for slicing.
