Abstract: A modular distribution assembly comprises a top plate and a bottom plate, each of the top plate and the bottom plate comprises a plurality of recesses. A plurality of support members are slidably coupled to each of the top plate and the bottom plate, each support member of the plurality of support members comprising a protrusion on each of opposing sides thereof, each protrusion slidably coupled to a corresponding recess of the top plate and a corresponding recess of the bottom plate. Related assemblies comprising the modular distribution assembly and related methods of forming the modular distribution assembly and the assembly are disclosed.
