Do I need to learn a 3D modeling software?

In my view CAD is always worth learning, especially if you understand what prints best on your printer.
FreeCAD is basically the worse possible beginners tools. Don't get me wrong when you learn it, it's good and comparable to professional CAD software. But the learning curve is dumb.
Learn the basics first. TinkerCAD is free (from Autodesk) and will get you started. But if you want something which would take you further Fusion360 is fantastic for beginners.
The workflow of CAD is as follows. Sketch -> Action -> Sketch -> Action. Lets say you want to make a box with a hole in it. Sketch the outer box -> Extrude it -> Sketch the inner box -> Extrude/Cut it.
I have to agree on that. I feel I can only use FreeCAD because I've taught myself SolidWorks years ago and I know what to look for when I want to achieve something. Or said another way, when I want to do something in FreeCAD, my though process is always "In what roundabout, convoluted way can I do in FreeCAD what I used to do in 2 clicks in SolidWorks?". The only reason it works for me is because I know it can be done and I know the intuitive way it should be done.
I kind of have the same issue in Blender: I've been trying to teach myself Blender for years, but no matter how hard I try, it's just not letting me in. Unlike FreeCAD, I have never known any other software similar to Blender, so I don't know what I'm doing - or rather, what I should be doing - and it's excruciatingly frustrating.
The commercial alternative to blender is software like Maya. But I too struggled with Blender, however I feel that's because 3D modelling is different from CAD, since modelling is like molding clay into the shape you want it in, rather than accurately measuring it out like in CAD.
Yes 3D modelling like in blender can be quite precise but it's a completely different mindset than CAD, much more about taking basic shapes and sculpting into what you want. Of course then there's the whole animating/shading/lighting and so on which don't exist in CAD at all.
I have trouble remembering what key pans and what key rotates view and the thought of actually figuring out how to manipulate the 3D file in FreeCAD felt like it was gonna melt my brain.
But thank you for the recommendation. TinkerCAD made me feel like I was playing with children's blocks but at least I understand them.
I also think I'm gonna try get started on learning something else after I brute force this stupid single print. And I think it will just be trying some of them out.
Yeah Fusion is the way to go, especially if you are learning. Lots of hate for it around here, due to Autodesk endlessly changing their policies. But there's no point in learning the basics when you don't know if it's you... or the software.
But if your issue is just navigating the 3D space in FreeCAD, you can set it such that it's the same in TinkerCAD/Fusion 360. FreeCAD calls it Revit, and you can set it in the lower right corner. Hold you mouse over it to show tool tips.
If it had as many 2 minute long tutorials on youtube explaining exactly the feature I was looking for as F360 does, FreeCAD would be the best case software
