Snug Can Lid

I designed this lid with a tapered opening and a ring to make it seal. V2 is designed to be thin for fast printing with a minimum amount of filament. V2 added a 2mm fillet added to the inside edge of the lid for a better bond between the wall and top. V3 Is thicker and stronger so it will last longer, but It takes longer to print and uses more filament than V2.
