Phone folded horn passive speaker

Redesigned sound port collector for universality. Base width is 65mm, so if your phone is 71mm, you need to resize it by 110% or slightly more. In width of course, but if your slicer give 110% to all sizes, it does not care and you can print it little bigger.

MK2 version have another hole for phones with speaker at the back side, so it is more universal. Is placed in STL at printing position.
