Gaggia Baby Twin espresso machine water tank seal backup ring

After only a few weeks the new seal began to leak as well, this is a backup ring to apply more sealing pressure to avoid the risk of water leaks. Printed in TPU works well. the tank takes more a bit force to put onto the machine, but that's fine. Might require x10 scaling, (stl from Autodesk Inventor issue cm-->mm). in hindsight this probably would have fixed the leak the first time around rather than buying an expensive replacement seal which only lasted a few weeks before leaking
