Tips on many cylinders, forming one (image example)

Hi all,
I’m back again, with another question …

I’m trying to make a cylinder and break it down to many cylinders to form the cores of a cable or stands.
Failing, either by making many that are hard to keep within a certain diameter of a cylinder or getting the right amount.

Any tips how I acheave the attached, s it has all the individual stands as a cylinder?
