Abstract: A modular shelving system is configured to store objects therein while having a customizable overall dimension. The system includes multiple modular shelf assemblies, each having a storage void, and a set of connectors. A first modular shelf assembly is configured to be secured, via a set of connectors, to a second modular shelf assembly and to a third modular shelf assembly. An additional storage void is formed between the first storage void, the second storage void, and the third storage void. The fourth storage void is configured to store objects therein. The location in which the first modular shelf assembly is configured to be connect to other modular shelf assemblies is selected by a user to meet the customizable overall dimension.
