I created it manually.
First I revolved a small circle to create a basic coil.
Then I split the coil along its length using the ‘split body’ tool. This created individual loops not dissimilar to individual links in a chain.
Then I simply detached a loop…
… then re-attached it by using the align too and rotated the loop by a specified angle.
Then I continued to do this for each loop to form a nice bend.
Using random rotation angles would give a more messy (and more authentic) looking coiled cable.
I used the align too because it immediately brings up the rotation option with the axis through the face (which is less tedious than selecting the rotation tool which would require repositioning the axis point manually each time).
Hope this was helpful
