Flexible arm material Answered

I'm looking to make a flexible arm that I can position however I want. I need it to have a fair bit of holding strength in that I don't want it to sag. It doesn't need to hold my body weight or anything like that and it can vibrate or move a little without being a problem. Immediately, two things come to mind: the plastic pieces used for coolant in machine shops that has now become a common material for something like this. The other is made up of stacked plates with a ball on one side and a socket in the other, I wire or something of the sort is put through it and a tensioning knob is used to pull it tight and keep it in place. Commonly, I see these in mag base indicators. I'd prefer to find the second one. Though, I can't seem to figure out what to look for in order to make my own. The best thing would be to find a modular kit that would allow you to make one fo any length (I need one that is about twice as long as a mag base indicator mount). Any thoughts on what or look for or anyone know where you could find something like this? P.s. this is going to be used as a way to hold a small screen. If it works well, I may adapt it to work for other things.

Look at monitor or TV mounts with an arm, the good ones come with a "ball" mount.
Basically just a pot with a hole that is a bit smaller than the ball.
The pressure from the screws on the plat fixes it in place - or keeps it slightly movable for adjustments.
Should be possible to make one if you don't want to buy one.
