Here's a standard 7C trumpet mouthpiece! It works pretty well. It's obvious when playing that it's not the same as a metal one, but it gets the job done.

Notes:

I'd recommend printing it on it's side (90° from standing up) for the most strength. Make sure to use supports "touching buildplate" otherwise it'll be a big mess trying to remove supports from the inside.
If you don't want support and are okay with it being easier to break, it will do fine standing up too.
