Speaker Horn for Nexus 4

Speaker Horn for passive amplification for the Nexus 4 phone.

I made the size to include the case that I have for my Nexus 4, so you would want to modify it to make it work for your phone. Works fine for the bare Nexus 4, but is loose.

I am able to run the volume at 50%, instead of being too quiet at 100%, so definitely makes a difference.

The hanger is for my car, your mileage / mounting will vary.
