I have always thought about getting LeBlond to make a lightweight but solid case. Trifibre do the LeBlond kind of thing. One of those with a CNC cut innner would be all you need unless someone else is chucking it into the back of an Artic every night. What is the EUB? I have my NS in an Explorer case which is great. Not sure of the model number but this kind of thing - https://www.explorercases.com/en/products/15416/15416-b-copolymer-polypropylene-waterproof-case/
