About this 3D model

Hey Folks! I had issues with the Topfill arrangement of my Vaporesso Cascade Tank. Sometimes it opened a little in my Pocket and a lot of liquid leaked.So i thought i design a quick Safetycap for it. it clicks on an of like a charm (at least in 90% of my prints) and is a quick print that can help you if you have the same issue like i had.
