Help with twist option

I have a problem with a twist option. I’m trying to create a door handle like this but I just can’t figure out how to use twist option right. Any ideas?

Hi Aleksandra - If your object us ‘flat’ at the start set the Twist axis to the center of each end face - sometimes it is easiest to mark with a line or two points. Then, once the axis is set, by snapping to the two points, you can twist the object ‘by hand’ interactively, or by typing in a number of degrees and Enter. More than 360 degrees is allowed.
