I have made a carabineer that is 3-D printable solving some of the problems that come along with 3-D printing. I have made a treaded locking nut that solves the fact that I can’t include a spring to keep the lever closed. This part can be useful in the everyday work of an astronaut. You can use it to attach things to your tool belt and various other things that have a loop to hook the carabineer through. It cannot replace the heavy duty uses of some carabineers but it could be used for the less stressful uses that will accompany everyday space life.
