Holiday light clip

My holiday lights came with built in hooks that work well to hang them, but they are flimsy, so I have had several of them break. I decided to design this hook to go over the base of each light and hook them into place.

The hooks were designed in DesignSpark Mechanical and I used Prusa slicer to convert to a gcode file. The hooks can be printed on an end (as pictured, or flipped over), but they seem to break easily along the layer lines. I ended up printing them with the opening of the clip down, with a brim and supports (see pic). This seems to make them quite strong, however, they do need some cleanup afterward. I realize now that making them with 100%, or near 100%, infill would make them stronger. This design was a little small for my particular lights, so I had to increase the print size 10% to make them fit properly.
