I've modelled parts with SolidWoks, first of all I've modelled thread M22 but when I print thread was so tight to work, I've re-modelled thread but I had to change thread diameter. Now female thread has a diameter like M22x2,5 and male has a diameter like M21. I'm aware there is nothing that has M21 thread in market but with these dimensions I'm able to have a working thread. So I don't bother if it suits with standard thread profile or not as long as it works perfectly.
