I am a graduate student that lives at Munger, and I noticed that at night my room wasn't completely dark: there was a little screen on the wall used to adjust the room temperature. There were only two buttons, one to increase the target temperature and the other to decrease, and there was no way to dim or turn off the screen. Thus, I decided to quickly CAD up a sliding cover and 3D print it, and now my room is fully dark at night!
Big thanks to the Shapiro Design Lab!
The original control panel. The screen gets very bright at night!
Showing off the design - fits like a glove!
