AIM controller wall mount

Simple wall mount for the AIM controller.

### UPDATE ###
Some said that it is pretty tricky to attach this to a wall. I managed to do it with a screw anchor, and an angled screwdriver, but yes it was fiddly.

But now I added a second part, to make it easire to attach it to a wall. It easily clicks into the AIM holder, and moves the hole to the side of the holder part. Just print it, click it into the holder and screw or nail the thing to the wall ;)
