Inspired by CSA Astronaut Chris Hadfield movie about cutting fingernails on ISS. I designed the case for fingernail clipper so fingernails won't fly everywhere but they get stuck in the case. Astronauts don't have to go to place where is air duct. They can do it everywhere they want, for example int the bathroom or sleep pod. 

The case is easy to print it, no support needed ( in first version), simple design, easy to assemble. I made two versions. First solution (case_for_nails_cutter.stl) is simple and should be assembled together with rubber band. Second one (case_for_nails_cutter_2.stl) doesn't need any additional rubber band. I recommend to print this version with two extruders with special filament for the support which disappear in the water.
