Need help with threads and possibly how to use derivation to create them

I am a complete novice both with 3d printing and designing the parts I want to print.
I'm trying to make a cup with a threaded lid. There will be a fabric disc placed in the bottom of the cup then the lid will screw on to hold the fabric in place. This is the link to my document:

antlu65 but I have absolutely no idea what I am doing or how to do it. I can get the thread on the internal wall of the cup but not on the external face of the lid.
I would VERY much appreciate some help and also how to print them without supports.

Looks like you have the right approach. Here, try this:

Thread Lab is a good feature, I had to tweak some of the values to get it to work. Ideally, you would want 2 or 3 starts instead of one so you don't have to sit there spinning the lid forever, but I could only get 1 to work.
Boolean subtract with offset is an important step for tolerances so that the lid will fit. This is also tricky when offsetting helical and filleted faces.
