All the components with the exception of the phone holder were designed to be printed without supports. I could not get away from the large horizontal span inside the horn so you should print that one separately.
The horn as an amplifier seems to direct the speaker output somewhat and increase the volume maybe a couple of dBm, Let me know what you think.
You can use Pan Plastite 0408LPP screws to fasten the lower angler to the cup or you can print them as one piece (CupBase&Angler.stl)
