My product is a zero gravity toothbrush for astronauts. This toothbrush has a comfortable handle for gripping and over 100 small bristles to clean their teeth. close to the bottom there is a intake port for water to come through. The bristles will be made out of PPHomopolymer. This is a material that is elastic, but is still stiff enough to clean their teeth. The body can be made with PLA or any other stiff plastic. There will be small holes between bristles to let water come out into their mouth. Once you're done, you can put a vacuum hose into the intake port and vacuum it out. This makes a no hassle process. The astronauts need this because a new toothbrush is needed about every 2 months. With this, you can print one anytime.
