I do some STL editing for 3D prints in blender, which I don't see myself changing, but I also design some cases, organizers, token holders etc for boardgames, for which it sounds like CAD would be a better fit. And yeah, as I said i did try it before but hit a wall and went with blender which I was more familiar with. Did the job alright, but perhaps was not the optimal way. I'll give it another spin with a different focus now.
