I am trying to get this cap to screw onto the end of this bottle.
I used the thread wizard and the same thread type on both parts being screwed together, but when I do a section view it doesn't look like the 2 parts would ever tighten all the way up. I figured I could just lengthen or shorten one of the pieces, but that doesn't seem to work. And I couldn't quite follow anything I googled.
I am going to 3D print these parts and want to print the ends with threads first to make sure it works before wasting time and filament if the threads arnt right.
