I am building an enclosure for a home energy monitor. This Project is being done with another user, where I am in charge of creating the CAD model and 3d printing of the the case/enclosure for the PCB.
I'm building a custom Macropad that has 4 keys in a "WASD" layout. Of course, you don't need to use it for those keys, but it makes it look familiar and organized. The Macropad has one rotary encoder for volume up or down and can even be pressed to play or pause audio. Additionally, a small 0.91" OLED screen can be used to display whatever you might want!
