There are places which will print out your model for a small fee on their own printer. There are even places which will allow you to use their printer if you come with your own filament (for example makerspaces) and maybe donate a little bit to support them.

As for CAD itself, there's a nonzero chance that someone already designed that part for themselves and you can download a ready model. If not, then by designing it yourself you're acquiring a skill that can be useful again in the future and you can share that model with others to get that warm fuzzy feeling that you've helped strangers who had the same problem.
