sling bag clip lock mechanism insert

I created this solution to address a problem with "Sling Backpack Cross Body Shoulder Bag Messenger Daypack for Travel Gym School and Driving" from Amazon. The bag uses an open squared hook to connect the strap to the bag, presumably designed for easy removal while wearing a seatbelt or parachute. However, this feature is not necessary, leading to the bag falling from your torso to the ground about every three hours of wear, testing the impact resistance of its contents. This solution fixes that issue and takes only 14 minutes to print, plus an additional two minutes to figure out how to insert it. The picture shows it inserted, nearly invisible after trimming, with a small gap at the upper corner. The initial version had insufficient space for insertion.
