I did not do this design. I found it on Thingiverse, and it was originally for hanging a longboard on the wall, which I printed some of them for, but I was looking for a latch hook to hold up the side discharge on my mower to keep it out of the way when driving it in or out of the garage, and for when I have the bagger attached. It works perfectly for this without any modification.
