A Better Customizable X-Y Tolerance Test

thingiverse

A far superior tolerance test that is completely unaffected by overhangs. The pins are held securely in place by a band at the center, allowing for a 1mm clearance all around. Turning the pins free requires an 8mm Allen wrench, and edges are chamfered to prevent first layer issues from impacting your results. A bonus benefit of the clearance is that the pins can also be moved slightly along the Z-axis. If the Allen wrench alone cannot free the pins, a small hammer can be tapped gently on either side to facilitate their release. After printing the tolerance test designed by Maker's Muse, I discovered that the print was binding on overhangs while the pin sections turned freely. To overcome this issue, I created this design in 123D. In contrast to the Maker's Muse model, which allowed me to achieve a 0.35mm clearance with effort, this design enables me to obtain a 0.2mm clearance with some exertion and a 0.15mm clearance with deliberate persuasion. ***UPDATE*** I decided to create an OpenSCAD version as well, allowing customization to suit your specific needs.
