iPhone 7 Plus Shower Holder/Speaker

I'm waiting for my Prusa i3 MK3, and I've been learning how to use Fusion 360. I don't even know if this is even printable. I'll definitely be printing this when I get my printer.

I often like to hear the news when I'm getting ready in the morning. I've often thought it would be nice to have an iphone holder that had a good horn on it. So I built this in Fusion 360 by measuring the iphone I have along with its case... so there might be give based on what case you have.

Anyway My hope is that the channel will pump the sound through the horn. If anybody prints this I'd love to know if it worked for you!
