SLA Printer Z axis limiter bar offset

After purchasing the KOYOFEI magnetic build plate (see picture) for my Anycubic Mono X 6K printer, I started running into an issue with homing the machine, where the build plate crashes into the screen before the Z limit switch is tripped, resulting in a grinding noise and an inability to zero the Z axis.

The issue was that the thickness of the magnetic surface and the new build plate were too thick for the Z limit switch to get tripped. 

This is a small printable offset that you can use to compensate for the thickness of the magnetic surface and the new build plate (3mm). 

To install it (on the Anycubic Mono X 6K), you will need slightly longer hardware (M3 x 8mm). 

1. Print the piece (I used one of my FDM printers/4 min print)

2. Remove the black plate that trips the Z limit switch from the printer

3. Reinstall using M3 x 8mm hardware: thread the new screws through the black plate and the spacer.
Note: the holes are offset to one side, so make sure to orient it correctly (flush with the edge and holes lining up)
