<p>update 7/10/22: &nbsp;I added chamfers to avoid first layer squish to the OpenSCAD. &nbsp;The prebuilt v2 suffixed stl files have this bottom chamfer.</p><p>--</p><p>update 7/9/22: &nbsp;I created this and posted it this morning then noticed salfter beat me to a very similar idea here.</p><p><a href="https://www.printables.com/model/189307-parametric-quick-tolerance-test/files">https://www.printables.com/model/189307-parametric-quick-tolerance-test/files</a></p><p>Very weird coincidence as I was not aware of his design when decided to write this. &nbsp;I like the tapers on his. &nbsp;I learned from that and integrated it into v2 of my code. &nbsp;His is a nice design where his retains the center rotating section with a bump out. &nbsp;Mine does not and the cylinder is free to slide out assuming there is adequate tolerance.</p><p>--</p><p>OpenSCAD code to easily pick your own parameters and generate custom stl files for testing.</p><p>outside shape is a hexagon to optionally print on it's side without requiring support and for a tool if needed to be held to break center cylinder free (tolerance too tight)</p><p>Screwdriver slot if the center cylinder needs additional force to break free</p><p>The outer hex does not change size when the tolerance is adjusted (default is 18.00mm across the corners; 15.588 mm across flats) . &nbsp; It is the inner cylinder diameter that changes with tolerance.</p><p>Different layer heights will have different tolerances. &nbsp;I wanted a simple and quick print to help me discover what my printer hardware, calibration, and slicer profile will allow.</p><p>I also included from 0.1 to 1.1 mm tolerance files in 0.1mm increments for reference.</p>
