SodaStream Jet to PCO 1881 / PET bottle Adapter

thingiverse

OK so soda stream bottle adapter's ... i printed ALL of them ... and every one i tried had some sort of flaw... The threads were the wrong angle, the threads were upside down, there were no threads, the threads were the wrong size, the wrong pitch etc etc etc. The main issues were binding, jamming or not sealing (my kitchen got very wet). So I stared for a long time ... then I looked up design specs and schematics. This adapter is for Sodastream Jet, (as sold in australia) with a tilt mechanism, a screw thread and retaining lip. There is no need for a seal as the adapter meets the same spec as a sodastream bottle without jamming. The bottle to be used with this is any that uses the PCO 1881 design specification (pretty much all soft drink bottles). The seal for the bottle mirrors the cap design for this standard and seals the bottle without the need for a gasket. I have knurled the base of the cap for easier grip but it spins pretty easily (at least on my print).
