Replacement zipper pull.
Assembly: pull the loop part through what's left of the slide on your zipper, then pinch the loop's arms and push them into the base. This might require a bit of force, but they will push through and lock inside without need for glue or anything else.
I would thing a small amount of super glue wouldnt hurt anything.
This is not my design, it was designed by: marqss on printables
I just wanted people to be able to print through the bambu handy app.
