Shower cubicle hook

I've tried a few different shower cubicle hooks, but none of them fit perfectly, so I decided to design one myself. I don't remember the brand or model of my shower cubicle, but maybe the picture gives some idea of what kind of cabinet this fits. The hook is meant to go on the outside of the cabinet and should hold things like bathrobes well.
There is a hole at the top of the hook, and it comes with a matching pin that allows you to connect multiple hooks together. This idea came up during the design phase in case the hooks don’t stay firmly in place and tend to move, potentially getting stuck in front of the door. However, in my case, the hooks snap into place quite firmly.
