About this 3D model

The tester can be printed all at once or separately, e.g. if you want to test two different filaments or two different settings. The full version is presumed to be more accurate, while the mini version prints more quickly. To test, slide the insert piece into the scale. Where it stops, the little arrow on the slider points to the number on the scale indicating your printer's tolerance for that filament and those settings. Where it moves freely indicates tolerances you can use for parts that are supposed to slide past one another.
