Ender 3 V2 Auto Bed Level using Servo and Microswitch

I'm tired of checking my bed level every time I print so I made this. It is working great!
I prefer this to BL touch because it is cheap and simple - I can easily repair it if there is a problem. I am an RC model enthusiast so I have all the parts in my bin and my experience in RC gave me confidence that I can do it.

If you are interested, note that you will have to do the following:
1. Print, trim and assemble the mounting parts
2. Install the servo and microswitch to the motherboard pins (I used the socket typically used for connecting BL Touch)
3. Modify and recompile Marlin firmware. I used the latest bugfix version of Marlin
4. Calibrate Z-offset so you will have a perfect first layer each time!
