Skadis Towel Hook

I needed a way to hang up a microfiber cloth on my Skadis panel on my desk, when I didn't find one I decided to try and design one myself.That didn't go to well since I am just a beginner in modeling so I remixed this design:https://www.printables.com/model/1076820-the-greatest-towel-hooks-v2-ikea-skadis by adding the Skadis hooks on the back and closing the opening that it had for the alternative way to fasten it to the board.
