I say similar because there is only the tip of the needle is only 1mm since the 90 degree angle
I need to find some kind of material I can get a wire of that goes inside the needle that will bend so it moves back and forward throughout the L shape of the needle and strong enough so it can push a springed metal present at the 2 or 3 mm from the tip of the needle.
I have the dilemma that if the material is too stiff it won't easily go back and forward because of the L shape but if it is not enough it won't have enough strength to make the spring to compress on the tip end.
I thought about a wooden snake alike solution but since the wire must be so thin I can't find anything to make it of.
Maybe you have a better idea.
Thank you so much in advance
