Sodastream to PET/Glass Bottle Adaptor (grabber)

thingiverse

The ultimate and Sodastream to small PET / Glass bottle adapter suitable for newer grabber style Sodastream machines. This design makes use of the inbuilt rubber seal at the sodastream machine end to seal the glass / PET bottle. No gasket is needed unlike other alternate adapter designs. Features: 1) Profile chamfered bottom lip that assist grabber style prongs to apply tension to the adapter and seal the bottle 2) In-built bottle thread-stop for correct internal offset and optimal sealing. By screwing bottle all the way to the end stop, your bottle will always be at the right position to engage the sodastream machine seal. No crazy strength needed to unscrew the adaptor as the thread is not the seal. 3) Reinforced outer diameter for optimal strength. 4) High bottle position so the injector reaches deep in the bottle. (does not affect carbonation but good for small liquid volumes) 5) Optimised for no required supports Tested with PETG and 300ml Schweppes glass bottle till the relief valve on the sodastream releases. Should work with PLA. I hold no responsibility for injuries from exploding plastic.
