Simple hook that uses a long 3M Command Strip. Easily holds up my heavy wool coat. Very shallow overhang, so you should be able to print with no supports.

*** Added second model that is wider/more aesthetically pleasing + has a removable cover for the 3M tab, hiding it while on the wall but allowing easy removal of the hook

*** I've been using this hook to hold two heavy, winter coats for over a month, and it is showing no signs of giving up any time soon
