You could make one.

Take a cylinder and make a cut at an angle. Make a few more cuts at opportune places. Continue until you get what you want.

It's a paper cup with a circular rim and a straight line bottom. It's circular if viewed from above, a triangle if viewed from, say, the north or south side and square if viewed from the east or west side. Sometimes used to illustrate the Christian notion of the trinity.
