Like so many people I began this project with help from the [zx82net] {https://www.thingiverse.com/zx82net) "Customizable Rugged Waterproof Box" (https://www.thingiverse.com/thing:3338826). I was further inspired by all the remixes and alternative originals. So, thank you all.

I don't have Fusion 360. So I tried using FreeCAD to modify STEP files. But that's a bit beyond me at the time of this writing. So I simply scaled up some STL files, shaved off some parts, cloned others, Frankensteined it, basically. Would really like to know how to scale in FreeCAD, so that's a future effort.

This box was purpose-built with a specific need in mind: To house version 1 of my River Science Kit. There's the Console and the Battery. I needed a quick and dirty container to put them in so I could carry them down to the river and do science. This gets the job done.

The seal is TPU.

As with any successful version 1, I'm already excited to modify everything into a version 2.
