ABSTRACT:
A stand with a rotatable tray positioned thereon. A race formed by a circular groove on the top of a base section and a corresponding circular groove on the underside of the tray permits the tray to rotate on ball bearings held in a ring and positioned in the race. While rotating, lateral motion is curtailed by flared tabs extending from the underside of the tray through an aperture on the top of the base section.
