Found among the ruins of ancient temples of Kali this gruesome cup is said to capture the blood of the living to give life and power to another who drinks from it. But surely such things are just legends.

Maybe one little sip wouldn't hurt.

This design is based on the Kapala cup from Spelunky which in turn was inspired by Indiana Jones which in turn was inspired by old timey adventure serials.

Print upside down. Supports shouldn't be necessary except in the nose. (and even then an FFF printer will repair it before it becomes a problem if you print without supports.)
