This is just a faux cap end for a small scuba tank that I use on my KISS rebreather. When I first bought the unit I thought the side tanks needed them. Why? Why not?! I finally remembered the idea and got around to making them. They should be able to be scaled to any size tank that’s not wider than your build plate if you happen to dive a rebreather. Many of them use tanks on either side of a scrubber case. You will have to figure out your own bungee cord attachment method, but there is a built in loop for it. Obviously this is purely a joke and has no real function at all.
