Abstract: A modular storage system for the storage of cylindrical objects such as wine bottles or the like is disclosed which features triangular modules which may be attached at their corners to one another to form a storage system. The triangular modules are formed by closely packed arrays of cylindrical tubes, each of which is so sized to hold a single bottle, or other object to be stored. Additional bottles may be stored between adjacent triangular modules, thus substantially increasing the storage capacity of the overall assembly.
