On my multi tool it is a toothbrush and toothpaste holder. This device would be useful because it wouldn’t take up any space at all.You would just have to bring a brush and paste to space and then after it prints, you would just put them onto the devices and it would work. This would be useful because it gives you more space to carry other items and it would hold your toothbrush and toothpaste in one. It’s important because your mouth is very important and you don’t want to get cavities. The toothpaste carton would have to be 4 inches or shorter. Another cool thing is that once you run out of toothpaste or your toothbrush gets dirty you can swap them out to another one. This is a multi tool because it has a toothbrush and toothpaste in one. Astronauts would use this in space because it doesn't take up as much space as a toothbrush and toothpaste would. And they are still human, and humans lose things a lot, so this would keep them in the same spot at all time.
