For a design like this you would need to provide full technical documentation.Although I guess it could be designed given some basic measures and information about threads.
If you could provide that, making something like that is possible.
Also I am not sure if 3D printing in steel is good enough to be 100% sure threads will be done in a required tolerance, and once assemblied that they will actually be functionable. If someone experienced could give some feedback about this I would appreciate it a lot.
