This bathroom supplies-holder is used to hold personal hygiene items. Astronauts can store a toothbrush, toothpaste, soap, shampoo, and/or medicine etc in it. It has five compartments for easy storage. It has a lid so things don’t escape. The lid is also for privacy, since the ISS offers very little privacy. Part of the idea is that the astronauts don't need to carry this holder with them as they travel to the ISS, which means less cargo weight. Later, once on the ISS, the astronauts can print the Supplies Holder, and have both the organization and the privacy they want for their personal belongings.
