This 2.2mm thick print is to be installed between your z-stop probe and the z-carriage on a Photon S when using a Sovol flexible build system. The Sovol instructions say that it will add about 2.6mm in height to the build plate, but I found (after trying multiple heights) that 2.2mm works best for my printer.

The good news is if you need a thicker z-stop spacer you can just change the height of this print in your slicer. I also replaced my screws with M3x8 to make sure there was a solid connection with the z-carriage.

I printed at 0.1mm layer height for accuracy with PETG on a Prusa MK3S+.
