Abstract: A tool organizer insert apparatus for a bucket holds tools, equipment, and similar objects within a plurality of round tubes joined in side-by-side alignment. The insert has an outer circumference which frictionally engages the inner wall surface of the bucket, leaving a center area of the bucket unobstructed and available for storage of larger objects not stored within the tubes. In certain embodiments the tubes are molded using a rigid, transparent, thermoplastic material, with each one of the tubes having a selected height and diameter. In another embodiment, the tubes are made of a relatively elastic material, allowing the insert some degree of flexibility in order to conform to containers of various shapes and sizes. In yet another embodiment, the insert and bucket are molded as a single unit.
