Simple hand free strap.
I recommend to install the layard in the clip first then the clip on the ring. To install the layard: first put the lanyard in the hole, it might be a bit hard, it's a tight fit to avoid any move, you can use a toothpick or some pointy to pock it through, but not as pointy as a needle. Then loop over the clip and secure it in the 2 little hooks on each side. See photos. That how I install it but may be you will find an other way haha.
Print it flat, it's easier
