Both ideas combined to achieve a slop-less thread fit, that is also smooth.   Thanks

I've printed 32 TPI 60 degree threads in PETG without much issue.  But my trick on assembly is to use silicone oil on the threads.  Then it screws right on.

 I do the same thing and I heat the plastic gently to about 140-180f with a lighter before engaging the threads.  This also helps to get a good tight fit.
