Bed Levelling and Z-Offset test

Previously I only ever found a test for Z-Offset (100mm square) or bed levelling, 5 squares. Realistically, I see no reason for these to be separate so I made this. It is sized for an ender 3 sized bed (I use a neptune 2) so the corners will be above the screws. Use these corners for adjusting level. The 100mm square in the middle is perfect for testing your Z-Offset.
