Haha! The waistline viewfinder has been pretty popular lately, so I decided to whip one up for fun. After several iterations, I’m finally happy enough with this borderless design to share it with the community.
Of course, feel free to leave a comment with any feedback you have—after all, the public’s eye is sharp and discerning; it’s only through everyone’s input that we can truly identify and address any issues.
You’ll need to purchase the following components separately:
1. Double-convex lens, 30mm diameter, 5cm focal length 1 piece
2. Fresnel concentric lens, 50x50x2mm, 5cm focal length, square shape 1 piece
3. Square mirror, 50x50x1mm (a 2mm thickness works just as well) 1 piece
Here’s my recommended parts list—but of course, you’re free to customize your selection based on your personal preferences.
