An under-desk mount for the steam controller. The steam controller and puck magnets are strong enough to hold the controller upside down as long as there's something holding onto the back to prevent it from rotating, and so that's exactly what this model utilizes.

As you can see the part holding the puck in is liable to break after removing/inserting a lot of times (which I was doing for testing), but it should hold up for a little while. If anyone has a better idea for the mechanism please remix it!
