Collaborative iteration is an optimization process by which a design is developed, built, tested, and then re-designed based on input from multiple individuals. 3D printing facilitates design evolution by allowing models to be built at a rapid pace. Numerous open-source 3D model designs intended for 3D printing are available through websites such as Thingiverse(TM). This paper provides an example of such collaborative iteration of the design and functionality of a simple 3D model, a series of interactive gears. The prototype model on Thingiverse(TM) offered a rough working of the gears. Users who downloaded and printed the model offered subsequent sequential improvements to gear teeth and spacing, iteratively improving the smoothness of the gear operation. Library makerspaces provide 3D printing facilities to a diverse group of students and facilitate their access to these open source model designs, allowing students to build, test, and re-design.
