HERO4 Session binocular adapter

This is a very simple adapter that allows a Hero4 Session (GoPro) to be connected to the eyepiece on binoculars. The eyepiece adapter fits my Nikon Aculon 10x50 binoculars, which have an eyepiece diameter of 45.2mm (approx). I needed to print this at x1.01 to get an exact size. Maybe I should tune my 3D printer :-)
