Fast bed level test pads (Prusa i3mk3)

Simple and fast pads for testing and setting bed level correction for Prusa i3MK3.
I am using mainly PETG and test is done with that
Outer lines of pads are 240 mm x 200 mm and therefore no skirt.
Pads are 0.2 mm thin and printing time is 6 minutes

- After assembling a kit I set all like said in manual and everything looks quite good. Live z adjustment was -180.
- I did some test prints and noticed that bed level corrections was better in
left 0, right -5, front -15 and rear -5
