Sunglass 57x18x140 (i am using)

I tried to pay attention to the standards while making the glasses. I designed it big for myself, you can make it smaller (5-10%) in scale. Before printing (as you can see in the picture), I found an old eyeglass and used its hinges. First I designed the hinges, then assembled and cut.

What do you need:
iron eyeglass hinge
Abs/Pla filament
Sandpaper 400/600/800/1000/1200

First of all, I tried many settings while printing the glasses frame. I tried to print with Ender 3 pro and Prusa i3. I got the output in abs with 30-40 mm per second. I fixed the problems on the surfaces of the printouts with sandpaper. The important thing is that the glass slot comes out well.

After you print the frame, you should find the company that can install glass on it and have it checked.

If you need help, you can write it as a comment. I'd be happy to answer.
