Snap-on narrow zipper foot designed for my Singer Sewing Machine. Should fit on Brother, and maybe other machines with the quick swap foot adapters as well as long as they are designed to attach with a 1/16" attachment bar and the width of the snap-on adapter is no more than 6 mm.

You will need a 1/16" gauge wire for the attachment bar, just slide through the holes and glue. I cut down the metal handle off a binder clip I had laying around, anything the right size will work.
