I like both my steam controller and my DualShock 4 controller, just depends on the game.

I got tired of having them lying around so I decided to find a way to hang them somewhere out of the way - the PS4 Controller Wall Hook Mount seemed like what I was looking for but of course the dimensions on the Steam controller are different enough that it warranted a different model.

I used the controller to adjust the dimensions a bit, and moved the hooks a closer together given the way that the grip is shaped.
