I redesigned the slider because the original one hurt my thumb and would easily fall out when unscrewed.

The new slider has a rounded hexagonal shape, and I added a small stopper to indicate the point where it might detach.

To assemble it, press the slider down while turning it in like a screw. This helps the stopper pass the edge and lock securely. It might feel a bit tight the first time, but after that, it goes in smoothly.

The end section next to the slider now aligns perfectly with the body for a cleaner, more precise fit.
