I have created a cover for a mini lightstick used in fishing (measuring 4.6x40mm). When designing it, I kept in mind the need to find zipper easily in a dark tent.. However, it can also be attached to other items, making it easier to locate in the dark or to follow someone.

The cover can be fully opened, but there’s also the option to partially close or completely close it if needed.

The assembly is quite simple. After printing, just place the "SCREW on the TOP, and apply some CA glue into the hole in the CORE part. Then, press-fit the TOP and CORE, making sure not to glue the screw — it needs to move freely. Finally, press and screw the core part onto the body. To disassemble, simply pull and unscrew.
