I remixed based on feedback to make mouthpiece touch the bedplate and make the airflow less restrictive.  I have not printed but it seems to slice correctly.  I haven't printed myself but there is one make!  Thanks and enjoy!

I recommend printing with support touching the bedplate only to avoid any support inside the mouthpiece or resonator cavity.  If it does print with support though, I suspect that it probably would not be too difficult to remove.

Enjoy!
