Specialized Scalpel

For the Mar’s Medical Challenge, I designed a scalpel with interchangeable blades. Scalpels are very important medical instruments that can be used for many things including surgery or to perform an emergency tracheotomy if someone’s windpipe is blocked. This scalpel is special because the astronaut can switch the blades out depending on the size or shape they need in different circumstances. The blades will be printed out of 3D-printable stainless steel, and can be reprinted after use so you can always have sharp, clean blades. The handle will be printed out of regular, colored PLA. It also has a hole in it so it can attach to a keychain and be ready whenever it's needed.
