3D texture on body surface

[PLAmenPRINT]

Hello,

I am searching a way to apply rough plastic 3D surface (like the image below)

on my speaker waveguide that I am goin to 3D print.

I found a video in internet that describe 3D surface mapping (from inserted image) in Solidworks which looks very useful but couldn't find any similar option in Fusion 360.

Am I missing something?

There is specific setting for rough surface in Cura slicer (fuzzy skin) that is with similar effect but it apply on all internal and external surface of the object which is not my case.

I would like to have it only on the black areas like the image below.

What could You suggest me?

Thank You

Regard

If you need a real 3D texture with such a fine structure, that cannot be done in Fusion 360.

In other applications this is done via displacement mapping.
