Here you go!
I'm not sure if this will have the design you're looking for, since I only did very basic searching. But this is the resource I use for all of my 3D printing model needs. :) Hopefully, it'll have what you're looking for! Your idea is pretty awesome though, so if I hear any information about something along the lines of what you're looking for, I'll be in touch. Wouldn't mind making one for myself!
Anyway, sadly, this section really isn't the place for this kind of question. So I'm going to close this thread for now. Sorry about that! Best of luck to you in your search. :)
