This device that i have made will be useful because it is a 4-in-1 tool. The name of this item is the File Tongue depressor Cotton swab Pick Device. The tongue depressor will check up what is in your throat and check your health. On the other side of the tongue depressor there is a file to sharpen items with it can also be good to keep your nails in healthy shape. On the side with a point it is a pick to clear debris from wedges of an item. If you attach an item that is included in the project and it is now a cotton swab to get your ears cleaned of wax. The item that you will print out will be nice enough to fit in the hand and be very usable on the trip to mars. You will mostly likely need to print this item about every week because this is to check up on how your health is. I think this item is worth to go on the trip to mars because instead of printing one item for one use, with the project i have made, print one item and has four uses.
