Sno-Yo
Team - MIT Undergraduate Student - August to December 2018
I acted as team facilitator in a group of six students throughout this project. We designed and constructed 50 yo-yos via 3D printing, Thermoforming, Injection Molding, and Machining.
Our goal was to design and manufacture 50 identical yo-yos.
I owned the 3D model of the yo-yo and modeled it using Fusion 360.
I supported quality control by checking molded parts against CAD specifications, ensuring consistency across all units.
The yo-yo stand and transparent dome were thermoformed using a 3D-printed mold, giving the final product its snow-globe aesthetic.
We added fake snow to the inside of the clear dome to further emulate a snow globe.
We successfully created 50 identical yo-yos and presented a report during an exposition we attended for our yo-yo design.
Beyond creating the final prototypes, our team analyzed the design for scalability and the potential for improvement regarding the DFA of our design. We identified inefficiencies in assembly, particularly in the number of small black internal components. Through design review, we proposed consolidating these into a single snap-fit part, reducing five separate components into one. This design-for-manufacturing improvement would have significantly reduced assembly time, cost, and potential for error if scaled to production.
