PET soda bottle coupler

thingiverse

Human: This versatile coupler attaches two PET bottles together, perfect for crafting funnels, hourglasses, or showcasing impressive tornado demonstrations. I'm talking about the standard 2-liter soda bottles you find everywhere, although it seems this top is also used on other sizes of soda bottles. Included with this OpenSCAD source file are many objects, but don't get too overwhelmed - the highlighted coupler module is what we're here to focus on. If you dive deep into the code, you'll notice a crucial piece called "PETtap()" which effectively taps threads onto PET bottle tops. As I test and refine more items, expect separate entries for water rocket nozzles and dog bowl fillers as they come off the 3D printer.
