Sodastream to PET/Glass Bottle Adaptor (grabber)

thingiverse

The ultimate and sleek Sodastream adapter, designed specifically for newer grabber-style machines that fit snugly into small PET or Glass bottles. This innovative design cleverly utilizes the built-in rubber seal at the sodastream machine end to create a secure and leak-proof connection with glass or PET containers. Unlike other adapter designs, this one eliminates the need for a gasket. Key Features: 1) A carefully chamfered bottom lip that helps guide grabber-style prongs into place, ensuring a snug fit and effective sealing of the bottle. 2) An integrated thread-stop on the bottle end, which guarantees correct internal alignment and optimal sealing every time. By screwing the bottle all the way to the stop, users can rest assured their bottle is perfectly positioned for engagement with the sodastream machine seal, without requiring excessive force to unscrew the adapter - the thread itself isn't responsible for sealing. 3) A reinforced outer diameter for maximum strength and durability. 4) An elevated bottle position that allows the injector to reach deep into even small liquid volumes (carbonation unaffected). 5) Optimized design requires no additional supports. Tested successfully with PETG and 300ml Schweppes glass bottles, even when pushed to the limit by the sodastream relief valve. The adapter should work seamlessly with PLA materials. Please note: users assume all responsibility for potential injuries resulting from exploding plastic.
