Well, the script seems to be working... (My superficial opinion anyway)

FALSE: I had to make the bottle hollow, otherwise got a helical ribbon with many bite marks on the edges.
(Using a solid bottle, the solid screw was formed by the booleans, but color of cuts matched the bottles, not the screw.)
Hollow bottle as cutter also worked...

Boolean difference is very slow. Several minutes for 50 bottles. 100 bottles taking "forever."

There is a lot of leftover surfaces after Boolean, but by selecting the screw, and hiding the "leftovers" the screw appears as a solid.

The Boolean difference needs to be done in smaller batches. 100 bottle screw, 180 degree rotation completed.
