Maker gangi-man 3D-printed an assassin's teapot, a vessel that can pour two different drinks from the same spout. It has separate internal chambers, and covering one of two air holes in the handle determines which liquid flows out.

The maker aimed for a design suitable for everyday use and spent about 14 hours printing it. After tackling leaks around an acrylic lid, the finished teapot successfully dispensed Calpis Soda and Amino Supli separately.
