Because there minimal gravity in space things like liquids tend to float around it can be hard to organised things. Fortunately, space agencies have accounted for this in a lot of areas like Velcro tables and toilets with suction. But when an astronaut wants to spit whether that is a mouth full of toothpaste or just a drink that they don't like they have to swallow it. This design is a two part print, there is a primary container and two slides. After printing all of the parts you slide the slides in the doors and link a rubber band to the nubs so that the slides will stay in when not in use. To use it you first open the first slide and spit then close it. Next you will open the second slide and let the spit float into the primary container. Close both slides and let the rubber band to hold them in until next use.
