LCD holder to fit the Zalman Z11 PC case

My pc is built in a Zalman Z11 plus, the case is brilliant. But I wanted to display the temperature at the top and at the bottom of the case as well as the average temperature within case, so I decided to make one with an Arduino Nano, a 16X2 LCD and two LM35DZs. This is the surround which fits in the smaller hole on the 5" bay covers. The surround fits the LCD well but could do with a dab of hot glue however I also included the original file for sketch up 2015, your welcome to edit and tweak it as you please. The surround snaps into the tabs which the original panel snapped into. For those interested in the code, I can post the link in the comments, just ask.

About the code.
The code displays the temperature at the top and bottom and displays the average between the two. It also can control the fans within the case using PWM and a transistor. so as the temperature rises, so does the fan speed which is displayed as a percentage. there is also a graph to represent the temperature as
