It is what it says - hat hooks.
I actually needed these so I designed a few different types. Number 4 is the largest which works for most hats. #4 also prints on the side for better strength. Any of these will be strong enough printed as they are though.
I tested one of these and they are darn strong even at 20% infill.
Enjoy.
