The Fidget Cube is a fidget toy designed by Matthew and Mark McLachlan, brothers and co-founders of the US design studio Antsy Labs.[1] It has fidget tools on all sides: a toggle switch, gears, a rolling ball (marble), a joystick, a spinning disk, a worry stone, and five buttons. It may help users with ADHD focus. It can also help children with autism and anxiety calm down or focus.[2]
