Hey Barry,
Here's my cheesy version. I wanted to setup a simulation, which should provide collision checking etc....But:
My opposing screw is still malformed for one. lol
But I also wanted to ask if you can share your process a bit deeper. Mostly with regard to the station count on your helical length, and also if you are using a slug "other" than the bottle (the one to be moved) to do the Booleans...
Your "bite curves" are beautiful and will help in the smooth surface creation. I HAVE gotten better results with higher counts, but still get SOME bad bites. Is there any magic you can share in this regard?
