Abstract: A rotating holder assembly includes a base, a strap assembly, a plate, and an accessory holder. The base defines opposing surfaces, an open-ended tubular portion located between the two surfaces, a cylindrical post coupled to and extending perpendicularly away from one surface, and a cap coupled to the outboard end of the post. The cap defines a substantially hemispherical shape having a diameter that is greater than a diameter of the post. The strap assembly includes a stretchable strap extending through the tubular portion, and a coupler for securing the stretchable strap into a loop of selectable size. The plate has a hole extending therethrough having an axial length that is less than an axial length of the post, and a diameter that is less than the diameter of the cap and greater than the diameter of the post. The accessory holder is coupled to the plate.
