This is a joystick concept I have playing with for a while. :-)
It is based on 3 potentiometers and an Arduino Nano.
I have tested with and it works very well. :-)
In the pictures I also added rubber bands to force it to the center.
The glue holds the rubber bands in place. Yes, it’s not a delicate solution, but it works. :-)
I also added a photo of a test with a drawing arm. I invented a very difficult way of drawing. :-)

6x M4x20mm and 6 nuts
4x M3x20mm and 4 nuts
2X M3x10mm and 2 nuts
3x potentiometers (B1 P160KN3K) I used 50K Ohm because I had those. See print screen for dimensions
