I sculpted this pendant from scratch using autocad. Goes great with his ring!
It is cast in antique bronze from my faithfully recreated 3d printed model, and then a patina was applied. For more information into the effort of how this was done, you can check out my build thread: http://www.therpf.com/f9/spaceballs-lonestars-medallion-schwartz-build-188710/
These are true to size from the film, and measure about 35mm, 1.4" in diameter
