Smartphone speaker passive "amplifier"

Smartphone support that should fit your Realme 8 or samsung S8 in horizontal position, and focus the sound towards you.

I have only tried a samsung S8 and realme 8, both fit fine, but anything larger that 162 mm may not fit. You can allways scale the support in Cura or sth to ensure it fits.

BTW, my smartphone only has a speaker on the bottom side, so it is probably useless to have two "trumpets" as this design has, but if your smartphone has speakers on both sides you will take adventage of this design.
