Phone Blaster (165mm Usable Space)

I made this phone holder to capture the output on my S24 Ultra left and right speakers. The design then channels the sound above and below the phone. The sound below goes into a lower chamber behind the phone and as well as out the front. Does it really enhance the speakers? I think it does a little. If you turn the holder left or right you can definitly hear how the sound moves in that direction. It does a great job holding my phone in landscape mode and a 20 degrees from the verticle. It does take about 7 hours to print. Tree support didn't work well for me. I switched to one of those back and forth lines. I also printed with the speaker hole up so I did need much support on the inside chamber.
