Shelf Hook

I had a few hats I wanted to hang off my 1.5" thick floating shelf so I spent a few minutes modeling this up last night.  Once it printed, it was clearly sturdier than I was anticipating… so I hung a backpack with about 10-15 lbs of crap in it to see if it would hold - and it does.  I'm still playing around with the design but figured I would post this in case anyone is interested.  

I printed the hook with 3 walls and 20% infill using PLA.  I will post any design updates I make.  Increasing the infill and using something like PETG would be better for a more robust hook - but I'm using these for hats/caps.
