[Printed parts] What is the thread profile on the M14 holes? #153

Closed JJ-White closed 2 years ago

JJ-White commented 2 years ago

I've designed my own M14 bolt in Fusion 360 to use with the OAT, but after printing without any added clearance it fits very loosely in the M14 threaded holes of the OAT and wobbles around. I've used ISO Metric Profile M14x2 when creating my bolt, does the model use a different profile?

Update: I've overlayed the STL on my bolt in Fusion and the profile seems to be the same. There does seem to be a massive 0.4mm clearance on each side, or 0.8mm in total. Is this intentional?

I've expanded the M14 thread of my bolt in Fusion using trial and error, and I've landed at around 0.13mm all round, so 0.26mm extra width in total for a tight fit.
