Due to shipping logistics for the prize, this contest is open to US residents only.

Full rules

• The cup must be able to hold at lest a 1/4 cup of liquid (no cup full of holes, you need to work for this).

• The cup must be able to drain the liquid inside (no printing half your cup, filling it with liquid, then sealing the top).

• The cup must be 3D printable on standard FDM printers. We are going to print all the cups to see how they work.

• Bonus points if the user cannot drink from the cup without spilling the contents all over themselves.

• More bonus points if there is a non-obvious trick that allows the user to successfully drink from the cup.

• Entries must be submitted before the end of April.

• A printable STL file must be submitted with your entry.
