I made this phone horn because my phone speaker has been on the decline. It seems to work pretty well and I noticed an a 10DB increase a couple feet away. 15% infill should be fine, Can also be sized down to fit on A1 Mini and still hold phone nicely.

*I designed this print to have 0 supports. It must be printed with the hexagons on print bed to achieve this. Enjoy!
