Hi everyone,

So I want to do a knurling on a flat surface for a 3D print (so it can't be a texture or an "appearance"). I also don't want the pattern to be on the entire surface (or face), I only want it to be on the area I marked in red in the image

So the model is attached, including an image of where I want the knurling to be.

Any advice on how to do a knurling on a flat surface?
