I tried to make a representation of my computer speaker but couldn’t figure how to make a cone rounded at top to fit on top to give the top edge a rounded look so I stuck a sphere poking out the top. LOL
This will hopefully be the worst I am going to be. I did like the look of my knobs though.
Compared to what others have done maybe I should of spent more time on this. 
But for a beginner I call it good enough.
