Found portable projector with case

I found this portable projector this afternoon around 2:15pm in the parking lot behind the Watertown Public Library on Oak Street. It's a compact black cylinder, about the size of a soda can, with a matte finish and a slightly scuffed top rim from travel. It came with a short HDMI cable and a gray carrying bag, and there's a blue sticker on the bottom that reads 'STEM Club - Property' which I thought looked like a school item. If this belongs to someone, I can arrange a quick drop-off at the library front desk.
