The file '2 Liter Bottle Neck Finish Model 3D Printer Model' is (f3d,stl) file type, size is 5.4MB.
As an exercise in learning Fusion 360, I have made this bottle neck that conforms to the PCO-1881 standard, used in many modern 2L bottles. If you just want to interface to bottles, I suggest you use laird's model.
