Eagle Scout project I designed and built a marimba (a musical instrument similar to a xylophone, but the size of a piano and made out of very hard wood). I CADed the overall design using AutoDesk Inventor and then designed a construction plan, invited over volunteers, and constructed the instrument with >300 working hours. Eventually it was donated to the local Middle School where I also volunteered as a music mentor and at the end of the year they featured it in their final concert.
