Anycubic Kobra 2 Max Silicon Bed Spacer - Spacers

The Silicon Spacer mod is intended to help flatten/level the print bed by enabling you to vary the depth of each bed mounted screw in an effort to compensate for variations in manufacturing tolerances.  Silicon Spacers found on Amazon typically all come the same size, and the spacers for the middle two bed screws on the K2M are longer than the perimeter.  

Printed with 100% infill at 0.16 layer depth

The 3d printed spacers should be installed facing down (away from the build plate) so that only silicon is in contact with the build plate.  This will reduce the chance of build plate heat affecting the spacer.  

How-to process for installing bed spacers can be found in the video below, links to spacers in the video description
