Plastic Bag Hanger

How irritating is it to have a plastic bag hanging from an hook and slipping off when you try to put something in the plastic bag. . .
Well, I thought it was irritating enough to do something about it.
First i made one out of wood, because i really like wood as a material.
Then i designed one in Freecad, and that is what i uploaded here as .stl files.

you up the lock, put the plastic bag in and down the lock. no more irritation !
