This project controls booster fan installed in my furnace ducts for each room. The case shown here is made to mount over a standard 2X4 electrical box. This case could be used for many additional projects. If interested, see my other project for the relay case which is controlled by this project. The case is made to hold the following hardware... 433 mHz receiver 2X16 LCD display DB-9 connector DHT11 Temperature/Humidity sensor Motion Sensor Arduino Pro-Mini (clone) Push button (reset switch) The receiver, temperature sensor, and Pro-Mini are friction mount. The lcd and DB-9 are screw mount and the motion sensor is glued in place. I have added 7 loops along the edge for wire management. The case measures... 4.5" wide 5.5" tall .75" deepI made this using a PowerSpec 3D printer using PLA. Found that the inside of the case needs to be painted BLACK because the Arduino and the LCD backlight, lights up the entire case. I guess I could use BLACK PLA but, I don't think that would look good in the room.
