Potentiometer broke off ultimaker 2

[Pakos 0]

So i am repairing one of my old 3D Printers ultimaker 2.

And i saw that the Potentiometer has broken off, lost the potentiometer, So i need a new one.

 

But there are too many different kinds of Potontiometers on the market. 

So i was wondering which kind of potentiometer i need. 

 

In the picture below(press the link) you can see what i mean. The green part i am gonna desolder and solder a new whole potentiometer.

But i cant seem to find a compatible potentiometer by my self. So can some one help me with finding one?

By the way, the potentiometer needs to click to select, and to scroll through the menu... And if someone can find one on Aliexpress or the type/brand. Please let me know.
