I made my own celtic skull stack and created a goblet topper! When I printed it, I used Cura. I also scaled the x - 200%, y-200%, z-220% to make the goblet a little more beverage friendly! My infill was at 25%. I used no supports. The goblet, using the z-220% scale measure 8 inches tall.

UPDATE: Version 2 has been added! It has a thinner lip/wall to the cup and a slight angle movement to the cup itself to straighten it up.
