This is a very soft version of the great X52 Spring Plate.
RabidRedRabbit, already made a soft version: https://www.thingiverse.com/thing:2405980
But I still want it a little bit softer. So I reduce the overall height thus compressing the outer spring only a bit. The inner spring will not be compressed at all.
I was not able to modify the original model, so I just made my own design based on the original file.
