Phone Speaker Amplifier - actually works

thingiverse

I created this simple phone speaker amplifier for my Xiaomi redmi note 9s. I have included the file without the hole for my phone so you can make the hole suitable for yours. I have tested it and the sound is much louder than without this thing. The hole is 80mm by 11mm which fits my phone with the included silicone case perfectly. If you don't know how to make th ehole for your phone hit me up with the dimensions you need and I can do it for you. Use tree supports for the hole section and print it standing on end.
