Disclosed herein are customizable kits of parts for the fabrication of polymer fibers. In some embodiments, the kits provided herein comprise a scaffold comprising first and second opposite surfaces and one or more pores extending through the first and second surfaces, wherein each pore comprises a first channel and a first conjunction interface. The kits additionally comprise a plurality of nozzles, wherein each nozzle comprises a second channel and a second conjunction interface, and wherein the second interface can be removably and stably coupled to the first conjunction interface of each pore while allowing a fluid through the first channel and the second channel. The kits further comprise a plurality of closure structures, wherein each closure structure comprises a third conjunction interface, and wherein the third interface can be removably and stably coupled to the first conjunction interface of each pore to seal the pore. In some embodiments, at least the second channel of each nozzle has an internal diameter configured to allow formation of a fiber.

Provided is an electro-spinning apparatus, which can perform spinning uniformly over the entire width of a manufactured fiber.
