Focusing Loupe Strap Holder

As I was looking for a ground glass focusing loupe for large format photography, I came across the PEAK loupe 1975, which is very well-designed and reasonably priced. But the loupe was missing an option to attach a strap in order to wear it around your neck.

My simple design adds this feature to the loupe. Simply unscrew the bottom ring, push the strap holder on the transparent barrel and screw the bottom ring back again. Finally, attach the strap of choice.
