The swivl tray was something I designed for the teachers at my school. The swivl product is something I did not make however I made an accessory tray for it. in short the tray goes onto the tripod meant for the swivl and teachers can put speakers or extra microphones on or in the tray. I wanted each tray to be unique to the class so I asked all the teachers at my school for a design. The tray above was made for my science teacher who really enjoys Spiderman. I had so much fun making these trays for teachers around my building.
