Tolerance Finder

thingiverse

For years, I've witnessed countless individuals wrestle with getting parts to fit together seamlessly. A reliable method for determining the optimal tolerance between components, or gap in the model, seemed elusive. I devised six distinct testers, each boasting a different range of offsets. All units are measured in millimeters. Typically, when working with two 3D printed parts, I've found that an offset of .25mm is necessary on one component (or you can get creative and add half to both parts). Similarly, if you're working with one 3D printed part and a non-3D printed counterpart, such as a metal rod or screw, a more modest offset of approximately .13mm is often required. These are merely ballpark estimates; actual results may vary depending on the machine, slicer settings, and nozzle diameter employed. To begin, select your preferred tester size plus 5mm Rod and 5mm Square Rod. Please note that some machines may necessitate different offsets in one direction (x) than another (y) due to subpar build quality. It's not advisable to print the testers with a brim; however, it's acceptable to use them on the rods.
