The Module first Aid-Kit is a interlocking design (with multi piece capability), made to save SPACE (hahahahahahahahah puns). Medical supplies should be brought on the mission to mars, the storage can be printed later. the Module First-Aid Kit is made to solve the problem of diagnosis on the mars mission. The box has a slot to label one section with a specific diagnosis. the module is small, yet capable to hold all supplies of one specific problem. Many boxes should be printed for various sickness and injuries. When an astronaut has an issue, they can easily go to the kit, remove a section, and cure what ails them.
