I made this support to hang my subwoofer under my desk to avoid kicking it.
It's made with the dimensions of the Logitech Z333 subwoofer and it has a hole in the back for the cables.
I'll hang it with some strong double-sided tape because I don't want to ruin my desk but if you're going to hang it with some screws you can make some holes in it.
If you put a speaker on it I suggest putting some foam under it to absorb some of the vibrations that could ruin the performance of your speaker.
DISCLAIMER: the project is a work in progress and I haven't printed it yet
Update 26/05/2023: I added some holes to use less material during printing and fixed some dimension errors
