"you need also a 4-2 pin flat cable best are the adhesive copper wall cable..."-->no need Since V3 version
i added also a hole for the charging port all you needs is soldering skills you need an( very small usb micro male)or solder 2 cable inside the module and a male small jack cable(you can change the module easyly) after setting all well you have to stick(with glue gun)"sssss.stl "with "Righto.stl" and" Lefto.stl"

V2 the module can't enter in for no reason so i enlarge it i am not going to print one more please tell me if it is working well... for the next version i may delete some useless part of the original model

V3I modified the head of the headphone because i used pla 40% infill perpendicular line and it BROKE (maybe also because of winter)
so changed the form of it and now after bending it is root and to ensure the bending resistance i used ABS (not shining in the dark);-( with 99%infill with concentric line and you as you can see in the bend test bellow.
i added also a hole for the cable and i used 2 of usb 3.0's under-cable
after testing (with an bluetooth mesurement app) this module can be used for 3HOURS...add a battery for V4?...
