Sunglass Frames, no metal

So I had some Sunglasses where the lens were still good but one of the arms broke. So I decided I should 3D print some frames. NOTE: I did NOT 3D print the lens!!!!!

This was incredibly challenging.
I started with trying to make a hinge that did not need a metal pin but could still be printed as separate pieces. I designed the hinge so that they would be very strong under tension at full open, as I knew they would be used in sunglasses.

Then when I decided I needed some kind of symbol on the bridge across the nose I decided to use a Tesla logo, but for some reason openscad refused to render the stl file onto a curved surface without producing flawed STL files. So I made my own Tesla logo file.

Then everything is curved which makes measuring it very difficult.
I think that one of the lens is about a 0.5 mm smaller than the other!!! very annoying, this version I did not adjust for that so one lens fits more loosely than the other.

So.....
this is not perfect, and it is DEFINITELY not customizable. Even minor tweaks will result in the lens not fitting. Obviously you will need to find the exact same lens if you want to print this yourself.

I feel like I have spent enough time on this for a while and it is time to take a break.
I am open to suggestions about ways to improve the look or functionality. My wife already commented that she does not like the color.

I personalized the arms with my name.
The curve almost exactly fits the curve of my face.
I maybe need to design the hinges so that they bend 110 degrees instead of just 90.

I am also indecisive about whether I like the thick arms or not. I don't think they are needed that thick for strength
