My project will be used for the astronaut’s ears. If the astronaut’s ear needs to be examined you need an otoscope. Each time you use an otoscope you need a speculum. The speculums can be 3-D printed as needed.
I think this is a great idea because if something happens to your ear you need to look at it and see what’s wrong. The ear may be at risk of problems during a space mission because of gravity and its effects on our balance system.
The astronaut who knows the most about ears or a doctor should use it.
