yeah after thinking about the base I was intrigued by the shape of that swivel part so I did that and all that was left was the wheel so I did that so I could have another piece for my library of parts. What was the method you used to model the top part (swivel part of the caster)? Also remember there are balls between the swivel and the base. This is what I ended up with the other day, obviously I am new to this maya/3d thing.
