Ikea KNAGGLIG box hook

Needed a simple hook for a kids book bag to hang on ready for the following morning, so quickly modelled and printed this. It is designed to clip onto one the top rail on the Ikea KNAGGLIG pine boxes (the large one). There is a small clip at the bottom to stop it popping back off by mistake. It slides along the rail nice and easily so you can add more than one and slide them across if they need more space for the items hanging on them. It is more than strong enough holding a book bag with several books in it, but you could easily increase the walls and infill or change to the Bambu strength profile to let it take much more weight.
