Since i love Hexagonal pattern, i've designed this one. It's a FULL REMAKE (only the shape is the same, this semplified a lot my work with a working model since the first print… THANKS Jacky!!).
You have to cut three stripes of transparent acrylic (those for documents covers), wide 13.8 mm, and slide it into the rails. There is a limiter so they stay in place. Cut the height 5mm higher.
