The hanger Shark provided was just too tall for the board I wanted to mount it on, so I made this one. This one is in PLA and seems to be holding up fine.
This is a Model HN175 ( https://support.sharkclean.com/hc/en-us/sections/8656275931164-HN175-Series )
Be careful, since Shark seems to make it their mission to require a different hanger or wall mount for every one of the million or so vacuums they make!
The author marked this model as their own original creation.
