These are some mounts and hooks and caps for a 13 mm rod. I got a wooden one from the hardware store.

With the hooks you can hang random stuff on the rod (unfortunately it's not working with humans).

The hooks snap on the rod, so they don't fall off everytime you get your stuff from there.

I also added the Freecad files, so you can edit it. I would recommend that you decrease the distance from the shelve to the rod. The current model is 10 cm which is a little bit too much I think.

Additional parts you need:

• 13 mm rod, you can choose the length
• for each mount: 2 screws with 4 mm diameter and a length of at least 12 mm

Sorry for the bad pictures, I'm lazy.
