Tough Tethered Container

I've noted many containers used for storing and carrying of items in the outdoors. I enjoy the outdoors in many ways, and created a design which has worked out well. I used heavy threads, thick walls, and a tethering system of my own design. I hate loose lids, and this is a simple way to keep track of said lid. The tether is simply 550 paracord, slightly melted, and after cooling, it's just enough to slide in the Lid slot. Then is passed through the Bottom tube. It's then melted again to retain it. This allows for removal of the lid, as the paracord can spin in the hole in the Lid slot center. This was printed with PolyTerra Forest Green. NOTE: I've tried PETG, and the threads are so tight, it will take pliers to get it apart. I'm working on a variation with appropriate thread spacing to accommodate. There is a ring groove made to fit a gasket to provide a simple seal, making it fairly water-resistant.Gasket Used: Mr O-Ring 222 Silicone O-Ring - 70A Durometer, 1-1/2
