I bought and no longer use a wireless cellphone charger and an extra cup holder. I used them in my 2017 MX, so I believe they will fit any pre-refresh MX or MS.
Here are links to them:

I modified the cup holder a bit so it doesn’t block the adjacent cup holder. See pics.
I am giving them away for free so long as you pay the shipping (which I am guesstimating at $10). First one gets them.
