Balcony Door Pull-Latch Handle

This is a fast-printing compact 3D-printed handle designed to let you pull your balcony door closed from the outside, using a clever slide-lock mounting system that works with an existing screw. Our balcony door didn’t have a way to grip or pull it shut from the outside. Rather than drilling or replacing hardware, I designed this snap-on mount that mounts securely onto a partially unscrewable bolt already placed in the door frame.Mounting MechanismThe key feature is a keyhole-shaped slot on the top.Because the screw can’t be removed entirely, I made the top of the slot open-ended. You slide the latch over the screw head, then pull it downward so the shank locks into the snug 4 mm hole below.Tightening the screw holds it firmly in place. No glue, no modifications, and it can be removed or adjusted anytime. Very renter friendly!Design FeaturesThe handle area at the bottom is rounded and slightly extended to give just enough leverage to pull the door shut comfortably.All edges are smooth
