This is an addition to the Simple Caddy model I made here https://makerworld.com/en/models/143303#profileId-155798

This model has nubs on the sides to attach two baskets which can carry a variety of things such as USBs, notecards, markers, and various other items

Using the 3mf it's a total of 203g for the entire print. The baskets are detachable and simply slides on top of the nubs.
