VESA or other mounting for small speakers

I'm in process of designing a small and light weight speaker. It's getting 3D printed cabinet and while drawing it, I had an idea. I could put in mounting points for wall-mounting. The VESA seems to be a nice standard, it's got patterns sizes for small and light weight stuff too. I'm using heat-set inserts for screw holes, that should provide enough strength to carry small speakers. There are many wall-mount arms to choose from if I want to hang my speakers onto something.

This spawned another idea. Should I still put them on the bottom plate? The load would be lower on the cabinets plastic, but this will rule out some booms. On the other hand, a good arm will rotate wide angles and the weight is low so should not be a problem.

What do you think? Is there some other standard I should go for?

I was also thinking of mic screw size, but that's a single screw so I don't trust that PLA holds. It would need a stand where the screw stops it from slipping, but it would rest on it's feet.
