Ikea desk "Micke" pencil basket that covers hole.

There is something similar over here (https://www.printables.com/model/637974-ikea-micke-desk-pen-holder), but mine has walls that stand out a bit. The idea is that stuff won't accidentally fall into it.

Created in FreeCad. I made the rim halfway at an angle so you can print it without support if you put the open side up.

Made for my daughter, who refuses to use it, because I forgot to ask her permission. Good point. Her desk, so she decides. This means the shown image is staged.
