How would you approach the modeling of a shape like this (circled in red)?
The goal is to have a model for CNC. I am still quite weak with modeling so I am not sure about how to address this. What I did for now has been extruding the shape vertex by vertex, trying to keep only quads, adjust the Z of some of them, adjust the crease and apply a Subsurf modifier.
How would you do this? Please without sculpting.
