Bugaboo Fox Cub Handle Hook

A remix of [bugaboo fox bag hanging hook by Ifrah](https://www.thingiverse.com/thing:4677011) to fit the nub in the middle of the handle of the Bugaboo Fox Cub.

I have not tested my prints of this to failure but I was able to carry the default contents of the Gladys Bag without issue. So a couple of kilos are probably fine with 3 walls and 8 bottom layers. Print solid with the side of the hook oriented to the build plate for added strength.
