Beverage tray for clumsy people

With this cup holder, you can transport any number of cups, as it is expandable. Through its design, it is almost impossible to spill drinks. The inner rings can be inserted into the 90 ° position and then rotate in the bearing position. The inner ring has an inside diameter of 68mm. 68mm cups also fit into the holder. Should other diameters be desired, I could implement this against a small expense compensation.

Tell me if you like it, and give me some feedback about it. Thanks.
