Dimension consistency test

I noticed that the precision of my prints has decreased in recent times, so I decided to investigate this issue further. To begin with, I printed a standard test cube to identify where exactly the problem lies. In order to pinpoint the exact moment when the discrepancy occurs, I created this pyramid structure. Upon closer inspection, I realized that the first step of the pyramid is slightly lower than the rest. Examining the leadscrew of my Z-axis, I discovered that it becomes increasingly difficult to turn at this specific height. Consequently, my test proved to be a useful diagnostic tool as it indicated exactly where the inconsistency occurs. This test also exists in a cylindrical format; check out the design located here: https://www.thingiverse.com/thing:3268341
