Astronauts can't bring a dentist table into a spaceship. So I decided to 3D model a dental tool holder. It has holes on each side so that you can screw it to a wall or a table. It has a bar on top so that no one can get hurt by the pointy ends of the tools and so that the tools won't fly out of the holder. The tool snaps into place so that once it gets into the holder, it can't get out again until you pull it out (with a bit of force).
