Sodastream CO2 canister adapter
thingiverse
I'm testing the feasibility of using Sodastream CO2 bottles as a safe alternative for mig welding safety gas. After scouring the web, I found numerous metal adapters available but surprisingly, none in 3D printed form. Given that the connection on the sodamachine is also plastic, I firmly believe a 3D printed adapter can be used safely without compromising the integrity of the system. To achieve this, I'm using a thread tap to create threads in the 6mm hole and then inserting a hose connector. A rubber seal may be necessary to prevent gas leaks during operation. With approximately 425g of CO2 in each bottle, I estimate around 217 liters of gas will be available for welding, providing roughly 30 minutes of continuous working time. This project is still underway, and further refinements are being made... (https://www.youtube.com/watch?v=na-xXCRlUBo)
