You will not find a tutorial that will walk you through making the part you want. But you will find one that starts out showing you how to make a 2D sketch And another that shows how to define dimension that are functions of other dimensions and another that talks about making "extrusions"
Actually the process is the same if you were to use FreeCAD, Solidworks, or Fusion. The location of the menu picks change and the lines use different color codes. But you really do have to start from zero and follow along or you miss the fundamentals. The part you want is very "geometric" so it will be easy to model, unlike say if you wanted to make a pair of scissors. So only the first half dozen video is needed. What you will find is that making the part in CAD is like making it in the shop. You start with custom extrusion then remove metal by drilling and cutting, then round off the edges. Many people come into 3D CAD thinking they are going to make a drawing of the part. No, you make a model of the part. Once you do 5 or 8 of the graduated example exercises it will make sense. But don't skip ahead. I'm actually watching a Solidworks online class now.
