This is a basic Pythagoras Cup, an ancient design that demonstrates the principle of a siphon. The cup can be filled normally up to the top of the center column. However, if the liquid level rises above the top of the column, the siphon activates and drains the entire cup through the bottom.

This model is designed as an educational demonstration of fluid dynamics and the famous "Cup of Pythagoras."

All 10 test prints of this model were successful on my printer without any modifications to the design. If the print fails, poor bed adhesion is likely the cause, so make sure your build plate is clean and properly prepared before printing.

⚠️ Important: This model is not food-safe and should not be used for drinking. Use it for demonstration and display purposes only.
