I 3D PRINTED A CAMERA LENS and the Photos are Amazing

I always dreamed to create my own lens. Collecting old and weird lenses is a passion of course, but sometimes I want to experiment with my own creations, even if I love to modify old lenses, here I wanted to look into the future. Wouldn' it be great if you could create a lens from scratches ? Wouldn't it be fun to experiment for really cheap ? Well, as I never really learned how to make 3D models on a computer, I started by making a cardboard first prototype with a found lens from 1890 I had in a box.
