There are similar designs around, but I remade this one from scratch.

The other design I wanted to print at first had a gap in the design and therefore didn't print well.
The other design also had 4 mounting hooks. With 3 hooks here, the cover is always centered and easier to mount/dismount.

I recommend printing this in PETG because of the better flexibility behaviour of the hooks. PLA might break - but I didn't test it myself.
