The design ideas I had would be the pop-socket itself and then piece with an extrusion that would wrap around your cup. The pop socket would have a slot and a channel that would allow the extrusion piece to turn and lock the pop socket into place. Then it would perform similar to the phone version where it would be held between two fingers. The popsocket would be made of three pieces of circular acrylic epoxied together. The first piece had a rectangular slot for the extrusion to go into, the second piece of a ring to create a channel for the extrusion to rotate, and a third sold piece to act as a cap. Again thinking of functionality, I thought this would be best applied to a shot glass. With large fingers, I often find taking a shot of alcohol troublesome. Sometimes my fingers get in my face and holding it (sometimes intoxicated) is a hassle sometime. So, I made the length of a wrap around piece the circumference of a standard shot glass. Of course I could have altered it with the circumference of other cups/ bottles. But for this project, I used a shot glass.
