The Printable Toothbrush
Going to space can be extremely time and money consuming. So when brainstorming ideas for the mars medical project, I took both of those facts into consideration. Astronauts have to be super vigilant when deciding what they are bringing on the trip, a pound can cost the International space station close to $1000. So with my toothbrush invention I used a replaceable, 4-sided toothbrush head. My toothbrush is compact and simple, and I finished off my idea with a hinged Brussels cover.
