Teach me how to apply 3D texturing to design files using Blender

I require someone to teach me how to apply 3D texturing to my design files using Blender for 3D printing.

We should go over using the shading options using node-wrangler, uv wrapping and displacement, and how to apply the texturing to select faces only.

Unfortunately I am unable to upload .STEP .STL .3MF files on this platform, but I will provide the files once the project has been accepted. We should go over a total of x3 design files of different geometries to ensure a good understanding. It shouldn’t take any longer than 1.5hrs, but realistically we could probably wrap up in under 45minutes for individuals with a good level of spoken English, and a good understanding of the software
