i bought a new-old panel and came up with this.
all the controls work now!
little write-up:
first of all, you need to get your hands on this particular panel (on the left):
(the one on the right is not suitable, as it's too much work)
the white bit you need to work with, holds this cable-bearing (or smth), which allows me to work with it easily(note the golden bullet-shaped stopper):
as you can see, it originally holds like this:
to change that, you need to remove all the somewhat machinery from the panel and then cut or melt the plastic bits from here:
then the white cable-bearing or smth will come off and you can cut it as shown in this picture:
then you will be able to position it to point upwards:
also, don't forget to cut or melt a little slope for the bullet-shaped stopper:
after you're done with cutting and then placing/melting the cable-bearing into desired position, it will hold like this:
and if it's needed, just find 2 extra cables and cut them like this, to later attach them together, to make the cable a bit longer
mine (original, 1-piece) works fine counter-clockwise, but it's rather stiff clockwise.. it's working anyway, so there you go
