I had not designed a coffee cup for a long time. The previous one was the Moebius Cup I think. So here is a new one. The Sphere Cup: This cup should contain 50ml of coffee, enough for an espresso. Its design is very simple: it is only made of spheres and planes. the advantage of the sphere is that it contains a maximum of volume for a minimum of surface. I used a new technique of modeling to insure a constant thickness and no sharp angle. I hope you will like it. Any feedback is welcomed.
