So I saw a couple of posts on these and wanted to try and build one out. I used a 1-1/2x1-1/4" PVC connector I believe it was called, and used a hacksaw and sandpaper to get it down to the inside rib which worked perfect distance wise for the view for the camera on my iPhone. I also couldn't find a proper size to fit snug so I had some camo fleece laying around and did a single wrap and it was the perfect fit to just keep it seated on my spotting scope.
I just need to camo it up now that it's all set.
