Question Texture Stretching

Hi.

I have been using the following setup to animate scrolling for the texture of my object. It's working fine but I don't want the texture to stretch if I resize the object (see on the resized cubes). I want the texture to repeat. What should I add to prevent stretching?

 

texture tiling affects that,
but depends on the model UV (so if you scale the model, uv will be stretchy..)

maybe this works though

or check for triplaner mapping "worldspace UV"

 

I have been testing and came close with this setup however I just cant figure out why only top and bottom doesnt stretch.
Side faces are still stretching. This is default cube btw.

Any ideas?
