A tripod quick release adaptor / mount / whatever you want to call it for Logitech BRIO webcam. Slips in snug as is, but you could add a rubber band or zip tie. Fits on the Amazon basic tripod, but should fit standard tripods. The widest part is 43x45mm
I've added another version where it holds the webcam arm/clip thingie folded up - see picture - the webcam is less wobbly this way
