Here is a 90% screen accurate reproduction of the Holy Grail from the 1981 John Boorman epic movie Excalibur. While designing the Grail, Boorman and art director Robert Pratt visited the Victoria and Albert Museum in London for inspiration, and decided upon a goblet with a highly reflective surface.  Dimensions: 18 cm x 18 cm x 20 cm (7" x 7" x 8"). The brim is not exactly what is shown in the movie, but it is a really good start. If you want the movie-accurate version , I am working on it, and it will be available to purchase in my store at https://buymeacoffee.com/lindsayreplica/extras. You can also purchase any of my designs there if you don't have a 3D printer.  If you like what I make and would like to support me so that I can make more models like this, you can always buy me a coffee at
