KF5 endcap based on the AWCY A3 collapsible brace

No real docs. But if you've made a KF5 and have made the collapsible 6mm rod stock/brace from AWCY? then you're good to. Push button is quite handy. And includes a rear QD hole for the days when the courts say it's not legal to have a brace, and you need to use a 1 point sling to brace against.
