3D Printed Hook - With Countersink Hole

After designing a 3d printed tie hanger, I was surprised at the strength a plastic hanger has. I decided to include a 3d printed hook to a shelf I was making and it did not disappoint. It can hold a good amount of weight and fits the aesthetic of the wood shelf.

Design:
-I included a countersink hole for the standard screws that I had.
-The hole is purposely small so that if the screw you have is bigger, you can easily drill out material.

Printing:
-You will need some supports for printing but not much
-I printed at around 64% infill. You could print at a higher infill if you need a stronger hook
-0.15 layer height
