I designed this for a quick fix.
Print without support, place a paper clip and snap the two zipper pull parts. You might need to hammer it a bit since it's a tight fit. No glue was required, but some superglue might be a more permanent fix.
If you print the base, you will have to fit the paper clip to the ring of the base first. Also, make sure to clip off any residual part on the original zipper for a smooth surface to glue on with super glue.
