Cura Scale & Horizontal Expansion determiner

This is (hopefully) a one-off method used to accurately determine the necessary adjustments to slicer settings before printing an actual part requiring precise mating or dimensional accuracy. The test part itself is straightforward. It features various geometric shapes designed to verify dimensions and cross-reference against design specifications, incorporating a 22mm hole for fitting a 608 bearing for added versatility. To achieve this, arrange the parts in a grid layout first - I opted for a 3x3 grid. Next, manipulate the model settings as follows: Scale the Y-axis at 100%, 102%, and 104% percentages. Apply Horizontal Expansion on the X-axis with increments of 0mm, 0.2mm, and 0.4mm. Print the parts, then proceed to mark or index them while still on the build plate before removal. Without this step, it will be impossible to distinguish between each part. Carefully measure each part and record the results in a grid pattern on a piece of paper for easy reference. Consult your completed documentation to determine which slicer setting yields the most accurate results, ensuring a successful print with precise dimensions and reliable mating capabilities.
