Sodastream CO2 canister adapter
thingiverse
I'm testing if Sodastream CO2 bottles can be used in mig welding safety gas. There is lots of metal adapter in web, but no 3d printed ones. I think that 3d printed one can be used safely because connection in sodamachine is also plastic. To 6 mm hole I'm making threads with thread tap and insert hose connector. Rubber seal might be necessary. 425g CO2 in bottle gives about 217 liters of CO2 gas and proximately 30 min. working time in welding. This is work in progress...
