This is a simple print to gauge what your print's thread offset tolerance is in Fusion 360. Thread used is 18mm M18x2.5 right-hand thread. This is what I use for most of my threaded models. The offset required will generally apply to other thread sizes as well.

***One, or more, of these sets may not work properly, that is the nature of this test. Please don't downvote if sizing is an issue.***
