This is a simple spacer for mounting Displates to a wall. It has holes for 1.5mm nails. It was used to add LED lights to the Displate as an indirect light. The spacing is suitable for mounting a Shelly RGBW2 LED controller on the backside of the Displate but may be used with any other LED controller that requires <17mm of space.
