Correct, if they have, or can create, a model of it. Since you have the cracked part they should be able to scan it.
I've kinda sorta wanted a 3d printer for ~20 years. I still don't have one because 1 - not cheap for something decent enough to really be useful, and 2 - I don't really have a need. Every once in a while I something comes up where I think one would be handy but there is always an alternative. Might be fun to play with though.
