I am learning Fusion 360 and planning to purchase a 3D printer but basically a noob in the field.

The burning question I have is, to make something like this https://www.youtube.com/watch?v=sFX26QuBAs8

[SOFTWARE] how highly skilled in 3D modelling do I have to be; beginner, intermediate or advanced?

[HARDWARE] will be there be technical issues printing what technically be a "cylinder" on its side?
how will the pieces be joined?

I would be most grateful if some light could be shed on these questions. Thank you.
