Bottle thread patterns

**This is not a complete thing for printing.** This is a helpful model for _your designs_.

### Where to use these patterns.

Well, use your imagination :) Here are my examples:

- coupling for a bottle and the funnel from the same bottle.
- tiny cans with colored caps. You'll not need to print the lids, just use them from the bottles.
- completely printed models - the box and the lid.
