Ikea Tupplur blinding curtain rope guide spare

A spare for a blinding curtain lower rope guide to be mounted on the window frame to prevent a hanging loop for kids safety. Should work for other brands as well, I think Ikea already changed the design to include the pull mechanism inside the curtain roll instead of the pull rope as our newer blinding curtains are without pull rope, but some other brands still have this design.
