Horn/Amplifier/Speaker for Xiaomi Redmi Note 3 Pro

Designed to fit a Xiaomi Redmi Note 3 Pro, and increase the volume of its speaker. Designed so I could more easily listen to podcasts while in the bathroom! Works great for podcasts, not so much for music, as the horn design makes the little speaker even more tinny.

*UPDATE 1* Have redesigned parts of the original design to allow for greater tolerances with the Redmi, so the fit in't quite as snug.

*UPDATE 2* Have uploaded a totally new design that allows the phone to lie flat while playin
