creating M6 thread

Recommended Posts

Created a nozzle box yesterday and just wanted to share my experience  on how to create a fitting printable thread.

When you just model the nozzle's thread (M6 pitch 1mm) it will not fit after printing due to shrinking. So I tested a few different sizes and the best method I found is:


- Cut of the sharp edge of the thread

- Scale the threaded hole by 105% in X & Y direction.

When you create the thread in autodesk fusion360 (free!) you have to mark the "modeled" box, else the thread will only be an image but not actually part of the model.


And here's the resulting treasure box .... with a special bottom compartment for the special nozzles :)

Thanks for the tip! Are you printing with supports? The slope of the thread profile is 30 degrees, so I would expect that you would need to. I'm trying to design a part with threads right now.
