About this 3D model

Made a mash up of my original panel and the one made by Chillance. I made a few variants but I have only printed panel 1. Panel 1 - Keypad, LCD and Fan speed controller with one switch. Panel 2 - Keypad and LCD only. Panel 3 - Keypad, LCD and a blank space for switches etc. Panel 4 - Keypad, LCD and two switches. Please check dimensions etc before you print them, the knob is a quick one I designed when I couldn't find one suitable.
