This All Purpose Hook has been designed to easily integrate into a multitude of use cases. So far, I've used my hooks to hang a fishing pole on the wall and as a wall mounted headphone stand.

The back of these hooks are specifically sized for use with Gorilla Glue Double Sided Wall Mounting tape, which does a phenomenal job of keep the hook firmly on the wall. I found it at CVS, and it is like the duct tape of renter's decor.

One hook took me about 2 hours to print. I like to print mine in batches of 3 which took about 5 1/2 hours. The hooks are designed so that the grain of the filament maximizes the potential strength. General rule of thumb, the more weight a hook needs to hold, the denser your infill should be. I used 80% which was probably over kill for what I was doing.
