I hacked my Phone SKope Go Pro adapter ...
My original Swarovski adapter actually broke when the wind knocked my spotter down, over and over two weeks ago. Split the rubber on my eyepiece, and broke the locking ring for the phone skope.
I took the connection square adapter and just taped it in place on the Nikon.

if you look you can see the tape holding it in place.
