I made this box to store batteries but, of course, it could be used to store anything. Not quite sure what’s exactly “sci-fi” about it, but it’s just what came out when I decided to design a sci-fi inspired box. Either way, it’s working for me as a box, so I thought someone else might be able to get some use out of it too.

The lid should pressure-fit. The tolerances for the lid and lip might be a little tight - as printed from my CR-10 mini, I have to use a little bit of force to get to clip it in to place.
