Directions:
Print two of the spool halves, and one of the splicer. Apply glue to the splicer, slide into one spool half, and slide the other spool half on top.
Not necessarily a necessary print, but I had to design one as a step for designing a desktop spool holder, and a sealed container for multiple spools, so I figured I'd at least share this.
The author marked this model as their own original creation.
