Once the alignment is set and the zip ties fully cinched, cut the zip ties flush on one side and leave about 1/2 an inch on the other. I cut them flush on the side of the helmet and left them 1/2 inch long above the center air vent.

I found that the zip ties, when encountering sharp bends eventually set into their final position and loosen up a bit. leaving the 1/2 inch of zip tie allows you to use a pair of pliers to grip onto them and tighten up if they loosen.

For safety's sake, use a lighter to melt the ends of the zip ties so they're not sharp and you don't cut yourself on them. Believe it or not industries that work with zip ties a lot actually have "Zip Tie Safety" classes. A sharp zip tie at eye level can do some serious damage.
