Fiber materials and textiles are topics of much research and study today, with efforts being made to produce fibers that are stronger, more durable, more breathable, and better for the environment. However, the production of fibers at the laboratory scale is uncommon and difficult past the prototype phase, and to a commercial fiber production level. Most current fiber spinning systems are too large to be operated anywhere outside of a designated facility and are prohibitively expensive. Here we present the build for a simple and affordable fiber collection device adept for demonstrations, student laboratories, and early research prototyping. This paper describes a nearly laboratory ready, functional fiber collection device that was designed, built, and evaluated during the COVID pandemic. It is constructed of an Arduino microcontroller, a toy motor, and basic circuit components with an assembled cost of ∼$60. The developed spinner's rotational speed ranged from ∼120−960 rpm. Spinner functionality was tested via fiber winding, solution spinning, and melt spinning. It is estimated that the spinner could hold ∼3.5 g worth of fiber before unloading and restarting with a fresh spool. Melt spun fibers produced by the unit were measured to have an average diameter of 31 ± 6 μm. Ultimately, this system was designed to be a low-cost entry point to fiber spinning for research and more primarily for education purposes. The parts list and system design are included and could be expanded upon as part of a learning laboratory exercise around the design/build/test paradigm. The current system works effectively as a demonstration to produce low-to moderate-quality fibers. The design would need to be augmented with a higher-torque motor, and certain components would need to be replaced if higherquality fibers are desired.
