Freewheel

Designing a 3D printable free-wheel was the final project in my product design course. Figuring out how the internal mechanisms work, and how much force the part could transfer was pretty interesting. Making and testing the actual freewheel was the most fun part. We 3D printed the part out of ABS plastic, and stuck it onto a skateboard to see how it would fair. The 3D printed part was surprisingly durable, and the ABS bushing actually helped reduce the amount of friction between the wheel and the shaft. The end goal was to design an even smaller metal version that could be put into skateboard wheels on powered skateboards.
