My design is a memory box. In space, it is really easy to lose valuable things, but with my memory box, astronauts will be able to keep valuable things in a safe place. In the box you can put valuable pictures and materials. The box is about 9 inches to about 5 inches. The average size of a picture is 6 by 4 so the astronaut can easily fit pictures in. Inside the box there are letters that have a hole in them. On the top of the box there are stubs to put the letters in. They are there so that the astronaut can put their name on the cover of the box. The whole is a snap fit so that the letters can fit securely. A material that you would need for this is plastic filament, the leftover stuff from the plastic used in the object printed.
