Airline Beam locking bar

This is a locker for the Airline Beam locking bars. When loading something on the bar, it can happen that the locking will losen.
To avoid this, I designed the ring that fits between the locker and the protective rubber around the bar. You can adjust the width of the locker ring just by changing the scaling of the Z factor. From my experience it is always something between 4mm and 8mm (it's good to measure it on your local airline beam bar).
