This is for fine tuning the elephant foot setting for profiles in Prusa Slicer. The squares are labelled with the elephant foot value being used for it. This helps with setting the right values in the slicer and for keeping track for the inspection afterwards.

Set a per-object setting change for elephant foot and set the value to the number written on top of the part. The pieces are optimized for 0.1mm or 0.2mm layer height settings. The prusa slicer project file included has all the settings per square already set. If desired a filament swap to a contrasting color can be added to the layer after z = 1.0mm. ie 1.1mm for 0.1mm layers, and 1.2mm for 0.2mm layers.
