I worked on a lens attachment kit for the iPhone 16 Pro for the last several months. Took a lot of time, nerves, filament and some sweat and blood from me :'). But I finally could upload this final version today and not only wanted to share some first pictures I took with it, but also a method for connecting printed parts to each other, that I personally haven't seen yet (second picture). I created an "U" shaped hole and extruded filament through the holes of the part that gets connected directly into the U hole. This created an extremely strong connection, much stronger than super glue or screws that would fit the parts.
