Roho water bottle to SodaStream

thingiverse

This adapter enables direct carbonation of water within a Roho water bottle using a Thermos and SodaStream. Frustrated by the need to transfer water from SodaStream bottles into my preferred Roho bottle, I created this adapter as a solution. A gasket will be necessary for proper function. Printed at 90% infill density, the adapter appears not to require a coating; however, it does experience minor leaks. To prevent such leaks and ensure structural integrity, I recommend applying a thin layer of food-safe epoxy, such as Art Resin. This adapter operates within a pressurized system; users assume all risk when employing it. During initial testing with an older printer, several prototypes failed under pressure. Designed using PTC Creo.
