I tried using that expression with my spacing field, attribute($currentfeature,'Horizontal_spacing'), in the Create Grid algorithm, but it still created a grid with the same spacing for all the features. It seems to be taking the attributes from the first feature in the layer instead of from the current feature.

I had tried to add an expression input as a child to the input layer with attribute($currentfeature,'spacing_field') and feed this in the spacing for the grid tool. When running the model, testing the expressions return the correct field values so if only it was possible to assign an expression input to the relevant parameters, it would work perfectly.
