The ideal setup for 360° and room scale for the Oculus Rift system is to mimic the HTC Vive setup of sensors on opposite sides of the room, mounted high, aiming downward. The included Constellation Camera stands do not allow the cameras to angle down far enough for my limited space, so I made these little adapters.

You just need to unscrew the camera from the rest of the stand (yes, they unscrew), and place one of these in between. I found, when printed with a brim, the fit was a little tight on that side. I found it fit best "upside-down" compared to the default print orientation.
